Katy Perry to appear in ‘The Simpsons’

LONDON - Singer Katy Perry will make a guest appearance in “The Simpsons” in a special live action episode which will see the animated characters turn into puppets.

The usually animated characters - which include Homer, Bart and Lisa - are to appear as puppets in a segment of the episode, which will air in the US Dec 5.

Perry will be seen playing the girlfriend of a cantankerous bartender named Moe, reports contactmusic.com.

The 25-year-old singer, who shot her scenes this September, will be joined in the episode by TV host Martha Stewart, who will appear as a cartoon version of herself.
