Rebel Wilson Is Jennifer Lawrence's Sister? MTV Movie Awards Host Spoofs 'True Life' (VIDEO)

Rebel Wilson and Jennifer Lawrence are related?!

Nope, this is not quite a Jenny McCarthy-Melissa McCarthy situation, but the 2013 MTV Movie Awards host joked about a connection to Lawrence in an unaired parody of MTV's "True Life: My Sister's Famous."

Wilson does a convincing job of playing Lawrence's identical twin sister Katherine who still lives in her hometown of Louisville, Kentucky.

"We are identical in every way except how we look and how we act," Wilson said in the above bonus skit from the 2013 MTV Movie Awards. "Jennifer actually gets a lot of her ideas for movies from me. This picture here is of a snowman that has a boner. And then what movie did Jennifer do? 'Winter's Bone' ... She actually gave me her Oscars dress. She said I could wear it as a scarf.

Wilson's post-awards spoof on the actress, who didn't attend Sunday night's show, was hardly her only shining moment from the 2013 MTV Movie Awards. "The Pitch Perfect" star also inserted herself into scenes from "Les Miserables" and "Magic Mike," performed a tune that combined Miley Cyrus' "The Climb" and Macklemore's "Thrift Shop" and had enough wacky outfits and facial expressions to keep the crowd laughing all night.

"True Life" airs on Wednesdays at 11 p.m. ET on MTV.
