Miley Cyrus will be making a brief guest appearance in the upcoming "Sex and the City 2" movie, but you'll want to rethink bringing along your children. According to GossipCop.com, the Hannah Montana star will appear in the R-rated movie alongside Kim Cattrall.

In the scene, Samantha Jones wants to look "hot and young", and winds up on a red carpet with Cyrus wearing the exact same dress. Samantha's sidekick Anthony thus yells out "Mother of God. She is wearing the same dress as Hannah Montana." This is followed by embarassment and possible cat fights.

The leaked scene has not yet been shot, but MTV reports that it will be filmed on October 16th. However, fans will have to wait to see if it makes the cut when the film debuts in May 2010.
