Here's one more reason to love Rebel Wilson ... she's related to Jennifer Lawrence! Kidding.

The hilarious Aussie stars in an unaired MTV "True Life" parody where she explains what it's like being the "Silver Linings Playbook" star's non-famous, identical twin sister.

Check out the clip below to see Rebel explain why it's not that bad being JLaw's twin, how she's helped the 22-year-old land roles ... and what she'd give up to be intimate with Bradley Cooper!

Warning: PG 13 content below.

We kind of love Wilson's brunette wig, and her attempt at an American accent.

Who wouldn't trade a body part for some one-on-one time with The Sexiest Man Alive? Pretty good deal ... right? What did you think of Rebel at the MTV Movie Awards? Sound off below!
