Normani and DeKaylin Metcalf have kept their relationship mostly low-key, but that changed on Thursday when Mr. Metcalf, an N.F.L. wide receiver, announced their engagement — at a news conference announcing his recent trade, of all places.

Mr. Metcalf, who had been traded from the Seattle Seahawks to the Pittsburgh Steelers, was speaking about his excitement to play for his new team when a reporter asked whether he had sought any advice from Russell Wilson, the quarterback who joined the Steelers last season on a one-year deal. Mr. Wilson had also played for the Seahawks, where the two were teammates.

During Mr. Metcalf’s response, he nonchalantly referred to Normani, the 28-year-old singer, as his fiancée: “I talked to Russ yesterday. I proposed to my fiancée. He’s the one that connected us, so he was giving us congratulations on that.”

Though some celebrities are strategic about how and when they share their engagement news, Mr. Metcalf, 27, seemed unconcerned about press politics. Instead, he ecstatically pointed at Normani, who was watching him from the side. “She’s right there,” he said with a smirk. “Hold that rock up, baby.”

It was a soft launch engagement of sorts. Despite making their romance Instagram official on a story post in July 2023, the couple had largely avoided the public eye. To many fans, the fact that they were even a couple was news. But it was happy news for R&B fans who have been rooting for Normani; she has been in the spotlight since she was 16, auditioning on “The X Factor” and then joining the girl group Fifth Harmony, and has opened up about heartbreak in her music.

At the news conference, Mr. Metcalf shared further details of the proposal, which he said took place the day before: “My family and her family was in Houston. It was my sister’s spring break, and just thought about getting the whole family together just for a big kumbaya and joining our families with a ring.”

“They got me good,” Normani could be heard saying in response.

The pair were introduced in 2022 by Mr. Wilson and his wife, the singer Ciara. “We hit it off from Day 1, and here we are,” Mr. Metcalf said.

In an interview with Rolling Stone ahead of the release of her sensual album “Dopamine” last June, Normani opened up about her relationship with Mr. Metcalf: “I’m happy. I am very happy. Definitely an answered prayer. I’ve experienced a lot with relationships. I’m a real lover girl. I wear my heart on my sleeve, and finding space where that’s reciprocated feels good. I like to see myself happy. I really do.” She added that Mr. Metcalf had inspired a few songs on the album.

Ciara shared her reaction to the couple’s engagement on TikTok, posting a screenshot from a video call where Normani showed off her ring. “@Russell Wilson and I knew when we introed yall 3yrs ago ..love was truly in the air! Now yall gon be booed up for forever!! This was the best news! @DK Metcalf @Normani we love yall so much!”

Some of the comments jokingly requested that Ciara expand her matchmaking services. For years, Ciara’s fans had also asked her to share the prayer she said led her to meet Mr. Wilson; they have been married for nine years.

Hollywood has had its fair share of successful matchups sparked by friends playing matchmaker. Prince Harry and Meghan Markle met on a blind date set up through a mutual friend. Nicole Richie set up her brother-in-law, Benji Madden, with Cameron Diaz. Ed Sheeran is responsible for Courteney Cox’s relationship with Johnny McDaid. Meghan Trainor and Daryl Sabara were introduced by Chloë Grace Moretz.

According to a 2025 study conducted by the Knot that surveyed nearly 8,000 engaged couples, 16 percent met their significant other through a mutual friend. This was the second most common way couples met; 27 percent of engaged couples met online.

“You just get that vetting and that vouching from someone else,” April Davis, the founder of Luma Luxury Matchmaking in New York, said of why meeting through a mutual friend can be fruitful. “If you’re introduced to somebody that has references, that’s going to tear down a layer of opposition.” A special concern of celebrities in dating is not knowing whether a partner’s intentions or feelings are genuine.

Though the prevalence of online dating has made it less common, meeting a significant other through a mutual friend has long been a tried-and-true method to find romantic prospects with aligned values. A friend can do the initial vetting for you, while making sure a potential suitor passes the vibe check.

So should more people set their friends up? Yes, Ms. Davis said — as long as the matchmaker isn’t blamed if things don’t work out.

The Food and Drug Administration issued a warning on Friday that advised consumers against inhaling nitrous oxide products such as Galaxy Gas, Baking Bad, Whip-it! and Miami Magic.

Recreational use of nitrous oxide as a party drug has long been prevalent, but whipped cream charger products such as Galaxy Gas have recently found a young and enthusiastic user base. Experimentation with an intentional misuse of the product has developed into a popular subgenre on social media, with widely shared videos of teenagers inhaling the gas from tubelike canisters of flavors like strawberry cream, tropical punch and vanilla cupcake. The videos have collected millions of views on TikTok, X and YouTube, despite attempts to limit searches for the product.

The name Galaxy Gas has caught on as a generic shorthand for these products, which the F.D.A.’s warning also says includes MassGass, Cosmic Gas, Hotwhip and InfusionMax. A wave of public concern has risen about the health dangers of these products, which are often sold in loud and colorful packaging that their critics say are appealing to teenagers and children. The F.D.A.’s advisory said the products could be purchased “at retailers, including, but not limited to: Amazon.com, eBay, Walmart, and at smoke/vape shops and gas stations.”

Advisories in the category of “Food, Beverages and Dietary Supplements” are not all that common, with the F.D.A.’s website only listing a handful in each year since 2021. In this case, the agency said it “has observed an increase in reports of adverse events after inhalation of nitrous oxide products.”

“The F.D.A. is warning consumers not to inhale or recreationally use any flavor of nitrous oxide in any size canister, tank or charger,” the advisory read. “When inhaled, these products can result in serious adverse health effects, including death.”

The agency, which did not respond to a request for comment, said in the advisory that inhaling nitrous oxide, commonly known as whippets, can result in health problems such as blood clots, asphyxiation, frostbite and psychiatric disturbances. According to the 2023 National Survey on Drug Use and Health, more than 13 million Americans have misused nitrous oxide in their lifetimes. Used as a recreational drug, the odorless and colorless gas can lead to feelings of relaxation and euphoria.

Britain banned recreational use and possession of nitrous oxide in 2023. Several U.S. states have laws banning the intentional misuse of the product, with some having laws preventing possession as well.

The original owners of the Galaxy Gas brand sold it to another company in the fall, and a message to the Galaxy Gas website seeking comment on the advisory was not immediately returned.

The website, which does not directly sell the nitrous oxide chargers but does feature an array of accessories for them, as well as branded merchandise including fanny packs, T-shirts and pot holders, has a disclaimer filled with warnings written partly in capital letters. One tells visitors, “It is illegal to purposely inhale our product.”
