The 25-year-old star left the ITVBe two years ago in order to focus on her health after she was diagnosed with crippling Crohn's disease but, despite getting her condition under control with the help of medication, her sister Billie doesn't think she'll ever return to the show.

Speaking exclusively to BANG Showbiz, the 26-year-old beauty said: "I don't think Sam will ever come back. I loved her on it [the show] but she's done everything she can. I think she's sort of grown out of it."

The former 'Celebrity Big Brother' star is busy looking after her seven-month-old son Paul Jr - whom she has with her partner Paul Knightley - and Billie is really enjoying watching her daughter Nelly, two, communicate with him.

Billie explained: "Paul and Nelly get on really well. Paul's really good, he's seven months now. So they've started to communicate more. Nelly was a little bit jealous at first but now she's a little bit older she understands more."

And, although Billie is tied up filming 'TOWIE', the blonde bombshell is desperate to have another child with her fiancé Greg Shepherd.

She said: "I definitely will have more children. Probably sooner rather than later. I would like at least two or three including Nelly. I want them to grow up together like me and Sam. There's only 11 months between us and we're really close."
