The biggest names in music were at The Forum in Los Angeles April 3 for the 2016 iHeartRadio Music Awards.
Jason Derulo hosted the show. He hit the red carpet earlier wearing an eye-catching bright red leather jacket. Later, in the press room, he posed for the cameras in a black leather jacket over a gray button-down short and black jeans. Other celebs who opted for classic black leather biker jackets included rappers Jake Miller and G-Easy and winner of the award for Latin Song, Nicky Jam.
Some men suited up for the occasion. Justin Timberlake didn't walk the red carpet but appeared on stage to present Taylor Swift with an award wearing a tuxedo jacket over a patterned shirt and black pants with brown boots.
Other men in suits included Diplo, Derek Hough and Matt Shultz. Mr. Hudson wore a bright blue suit while Nile Rodgers opted for white. Radio personality Elvis Duran stood out in a tropically patterned suit by DSquared2.
Some men, including Fetty Wap, Cody Simpson, A.J. Mclean and T. Mills kept it casual but trend-right with denim jackets over T-shirts, jeans and sweats.
