Kim Kardashian -- baby bump and all -- will hit Sunday's MTV Movie Awards to introduce [article id="1704408"]Selena Gomez as she performs her new single[/article], "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 [article id="1699495"]boyfriend Kanye West[/article] 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, [article id="1705176"]Gomez told Ryan Seacrest[/article] 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."
