Prettiest dresses at the 2018 iHeartRadio Music Awards

The 2018 iHeartRadio Music Awards red carpet was one big party!

Music's biggest stars showed up for the annual award show -- which is basically one big, rockin' concert -- on Sunday night. The dress code is usually your sexiest attire and of course, celebs didn't fail to impress.

Co-host Hailey Baldwin sent races pulsing in a super sheer Zuhair Murad look that left little to the imagination. Jenna Dewan-Tatum donned a more conservative look from Zuhair Murad, but nonetheless looked absolutely stunning.

"Modern Family" star Sarah Hyland took the plunge in ea sequined Galia Lahav that showed off her toned stems. She put all the attention on her flawless figure by putting her long brunette tresses up in a low chignon bun.

Meanwhile, Laverne Cox dazzled in a Rachel Zoe creation, Paris Hilton was red hot in a Charbel Zoe Couture fit-and-flare dress and Isla Fisher was a bombshell in Balmain.
