Actress's bump is concealed in raunchy shots
The pregnant actress regularly stripped off for the first season of ITV2 programme.
But shooting the follow-up proved a little more difficult.
‘She’s avoided doing the really graphic scenes and the others have been shot from an angle so you can’t see her bump,’ says a source.
Billie, 25, and husband Laurence Fox, 29, are expecting their first child later this year.
