Sunday marks the 2018 iHeartRadio Music Awards, and Hailey Bieber is this year's host.

The 21-year-old supermodel will m.c. the event with DJ Khaled in Los Angeles. Together, they'll introduce performances by top artists, including Bon Jovi, Ed Sheeran, Cardi B, Camila Cabello, Charlie Puth and Innovator Award honoree Chance the Rapper.

However, Baldwin isn't the first supermodel to take on a hosting gig. While some models have served as one-time hosts for annual events, others have hosted entire TV series. Gigi Hadid, for instance, hosted the 2016 iHeartRadio Much Music Video Awards while Heidi Klum has hosted Project Runway for 16 seasons.
