All eyes were on Jennifer Lopez at this year's American Music Awards, and, more specifically, on her super-toned abs that she flashed in a daring Reem Acra dress.
The blush coloured cutaway frock with ribbon detailing looked amazing on the singer, and showed off her washboard stomach perfectly.
But J Lo wasn't the only guest daring to bare their midriff. In fact, this was definitely the runaway trend of the evening, with Taylor Swift, Heidi Klum, Gigi Hadid and Charli XCX all opting to expose their tummies in cut-out frocks.
A long term fan of the crop top, Taylor Swift looked elegant in a mint green number by Michael Kors, while Heidi Klum opted to show some thigh and midriff in this black and glittery pink Versace dress.
It looks like the crop top trend isn't going anywhere anytime soon, so excuse us while we go and do some sit ups...
