Kim Kardashian is set to present at the 2013 MTV Movie Awards.

The 32-year-old reality star - who is due to give birth in July - will attend Sunday's MTV Movie Awards to introduce Selena Gomez to the stage as she performs her new single 'Come & Get It' for the first time.

Selena, 20, is geared up to do an ''earthy'' performance when she takes centre stage at the event, which is hosted by Rebel Wilson.

Speaking to MTV, Selena said: ''We're doing it kind of the theme of the video, which isn't out yet. It's going to be very earthy.''

MTV has confirmed today (10.04.12) that hunky actor Brad Pitt, 49, will present the Movie of the Year award at the event and Peter Dinklage will make a special appearance to hand the Comic Genius Award over to Will Ferrell.

Alongside the mother-to-be, other presenters include Steve Carell, Melissa McCarthy, Zac Efron, Kerry Washington, and Amanda Seyfried.

This year's ceremony is guaranteed to be a huge night thanks to the string of A-list celebrity presenters, an earthy performance and the new 'Best Shirtless Performance' category.

The MTV Movie Awards will air this Sunday (14.04.13) at 9:00 p.m. ET/PT.
