Kim Kardashian (And Her Baby Bump!) Coming To MTV Movie Awards

'Keeping Up With the Kardashians' star will introduce Selena Gomez's performance Sunday night.

Kim Kardashian — baby bump and all — will hit Sunday's MTV Movie Awards to introduce Selena Gomez as she performs her new single, "Come & Get It," for the first time.

The "Keeping Up With the Kardashians" star, who fans recently saw on the big screen in "Tyler Perry's Temptation," joins Melissa McCarthy, Zac Efron, Chris Rock, Steve Carell, Amanda Seyfried, Seth Rogen and Brad Pitt as presenters. Although she's made numerous public appearances since boyfriend Kanye West announced in December that they were expecting their first child, fans will undoubtedly be excited to see the reality star's sexy-mom style when she takes the stage Sunday night.

Earlier this week, Gomez told Ryan Seacrest that she's planning a downright bohemian performance for Sunday night. "We're doing it kind of the theme of the video, which isn't out yet. It's going to be very earthy," she said Monday, sharing that she'll likely wear her hair in "really cool braids" and it will involve a lot of fabric. "I know this is a big chapter for me."

The 2013 ceremony promises to be a huge night, thanks to a bevy of celebrity presenters, not to mention new categories such as Best Shirtless Performance and Best Scared-As-S**t Performance. Monday's screening of "This Is the End," followed by a Q&A with stars Seth Rogen, Craig Robinson and Danny McBride, kicked off Sneak Peek Week, during which MTV is offering fans an early look at some of Hollywood's most highly anticipated new movies leading up to Sunday's show. Tune in tonight for an exclusive sneak peek at "The To-Do List," starring Andy Samberg, Aubrey Plaza and more.

Who will take home top honors at the MTV Movie Awards? Don't just watch to see who wins, help decide who does! Voting is still open right up until the ceremony begins Sunday at 9 p.m.
