From Mike Tyson’s hyped-up intro for Madonna (who knew the singer let the boxer perform on her new album?) to Justin Timberlake’s sweet shout-out to his wife Jessica Biel and baby on the way, host Jamie Foxx‘s controversial Bruce Jenner transition joke along with crazy collabs like Madonna and Taylor Swift, the 2015 iHeartRadio Music Awards ceremony was jam-packed with memorable moments. Last night’s fashions were just as notable with cut-outs and colorblocking setting the tone. The fellas didn’t shy away from bold looks as many opted for unconventional suits and flashy streetwear getups. A lot of attendees were probably a little tuckered out because they also stopped by the Kids’ Choice Awards on Saturday. Scroll through the slideshow above to see what the stars wore both on and off the stage.
