Then it was Anne's turn. Having picked Miley Cyrus' Wrecking Ball, it could have daunted some but not Anne. She took the whole event incredibly seriously and aped the exact dress of Miley's video, wearing white pants and vest top. She even slicked back her hair and long white finger nails and licked a hammer, of course.

Hosted by LL Cool J and Chrissy Teigen, the Lip Sync Battle show has become a viral phenomenon with many A-listers taking to the stage to see if they can win. So far the likes of The Rock, Justin Beiber and Anna Kendrick have all taken part.

You can watch both battles below, although we can't decide who really won. The only thing would have been in Meryl Streep showed up to critique them.
