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, according to reports.

"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.
 

"And we really enjoyed their time with us, until we realized we were both old enough to be their fathers."

One Direction's "Family Guy" debut, in which Stewie scares

the lads with a tale about non-skinny jeans, will air in May (16).
