The former 'The Only Way is Essex' star has admitted little 19-month-old Nellie, the daughter of her sister Billie Faiers, doesn't quite understand her new cousin Paul and has started to show signs of the green-eyed monster recently.

Sam explained: "She doesn't completely understand but she knows she's no longer the baby in the family."

Sam's partner Paul Knightley added: "Where I can't give her my full attention as Uncle Paul she's getting a bit needy. I was in the kitchen with the baby the other day and she looked up at me as if to say, 'What about me?' So I picked her up."

And it's no wonder Nellie is envious of the three-week-old tot as her mother Billie can't stop cuddling the little bundle of joy.

Sam said: "Billie is the baby hogger! She loves a cuddle and then she won't let go.

"I said to her, 'Does it make you broody?' She told me that as a much as it does, she's also got the baby to enjoy."

However, Sam doesn't think it will be long before Nellie has a little sibling to play with because Billie and her partner Greg Shepherd, who have been dating since 2013, will probably have another child in the next "couple of years."

She added: "In the next couple of years, she'll have another."
