She may be just three shows into her first-ever headlining tour, but Megan Thee Stallion looked all the part of a seasoned star onstage Saturday night at Little Caesars Arena.

Five years after breaking big with “Hot Girl Summer,” the Grammy-winning rapper has embarked on a transatlantic arena tour of that same name, with Detroit an early stop on the run.

A sellout crowd was there to greet the 29-year-old Houston hitmaker for what was a girls-night-out kind of affair, with many fans arriving at LCA in their own variations of the curvaceous body suits and flesh-baring monokinis Megan Thee Stallion would embrace onstage.

It was a night writhing with snake imagery, sexual bravado and near-nonstop booty shaking. The show was as much about Megan’s confident, assertive presence as it was her ever-growing repertoire of kinky hits — a salvo that started Saturday with her latest chart-topper, “Hiss,” and its barrage of cleverly barbed celebrity shade.

Joined by eight dancers who at one point joined the star for a synchronized twerking number, Megan Thee Stallion kept the pace upbeat and the downtime minimal. The only extended pause for breath came with a mid-show segment in which she invited groups of excited fans — her Hotties — onto the stage for their own personalized dancing exhibitions.

Amid the extravagant raunchiness that often bordered on camp, that was a touch of come-one, come-all togetherness and accessibility, much like the assorted selfies she snapped on audience members’ mobile phones throughout the night.

As a rapper, Megan Thee Stallion is formidable — she built a name via her electrifying freestyles, after all — and her rapid-fire rhymes accentuated songs such as “Sex Talk,” “Kitty Kat” and “Stalli.” Elsewhere, numbers like “Thot S—” rode high on catchy hooks, with the likes of “Big Ole Freak” becoming arena-wide chant-alongs and “BOA” serving up her distinctive brand of side-eye.

After reported technical glitches on the tour’s opening nights, Saturday’s mix was crisp and full, and the star’s mouth-twisting vowels and spicy wordplay were only occasionally lost in the sonic boom.

Megan Thee Stallion’s trademark, defiant swagger did give way to a little vulnerability with the recent single exploring her battles with depression, “Cobra,” which wrapped up the concert’s opening segment.

“Wanna Be,” with guest Glorilla, and the 2020 Cardi B smash “WAP” helped the show start a crescendo that finished with the biggest hit of Megan’s career, the Beyoncé-featuring “Savage.”

For all the night’s energy — and props to the likable Megan, that rarely flagged — the show threatened to become a monotonous affair, offering few variations in sound, movement or expression. At a crisp 85 minutes, it clocked out probably exactly when it needed to.

Rising rapper Glorilla had kicked off the evening with a 45-minute set of Memphis-fueled hip-hop and her own brand of self-empowerment.
