One Direction will appear on 'Family Guy'

One Direction stars are getting animated for a guest appearance on hit cartoon comedy "Family Guy".

The "Story of My Life" singers will gather around a fire for a camping scene with troublesome cartoon baby Stewie, voiced by series creator Seth MacFarlane. But not all the boys have lines in the scene - only Liam Payne and Louis Tomlinson recorded their voice for the episode.

"There are not a lot of shows that, in the same season, feature guest-star appearances by both Frank Sinatra, Jr and One Direction," executive producers Richard Appel and Steve Callaghan said in a statement. One Direction's "Family Guy" debut, in which Stewie scares the lads with a tale about non-skinny jeans, will air in May.
