Barbara Windsor is guest starring in Come Fly With Me.
The actress is making her first small-screen appearance since she bowed out of EastEnders in September in the BBC One comedy, created by Matt Lucas and David Walliams.
Babs plays herself in the mock airport documentary, alongside David as executive passenger liaison officer Moses.
A TV insider said: "Moses looks after Barbara in the first class lounge, but it doesn't go according to plan."
Barbara, who follows in the footsteps of previous guest stars Geri Halliwell and David Schwimmer in the comedy, makes her appearance in tonight's (January 13) episode.
Show creators Matt and David have previously defended the show, following accusations of racism with their portrayal of ethnic minority characters.
