The former 'The Only Way is Essex' stars have been the best of friends for years, but it seems there's some tension between them at the moment because Ferne launched her rival pregnancy show 'First Time Mum', which aired two weeks ago, on the same channel as Sam's on-going series 'The Mummy Diaries'.

A source told The Sun Online: "Their fallout first started when Ferne told Sam that she had landed her own pregnancy reality show. Sam felt like Ferne was trying to emulate her success by launching a rival programme - and it made things awkward between them. Ferne was never going to turn down the show as it was an opportunity for her to make money for [her daughter] Sunday but without Sam's support the breakdown of their friendship was inevitable."

The pair sparked rumours that they'd fallen out when Sam - who welcomed her second child into the world in November - decided to announce the name of her daughter Rosie just an hour before Ferne's show debuted on ITVBe.

She was also not present at the at-home screening the 27-year-old part-time 'This Morning' presenter organised - but her sister Billie Faiers was there to support her.

Although the 26-year-old beauty is fuming with Ferne, ITV have already decided to commission a third series of 'The Mummy Diaries', but this time the show will follow both Sam and Billie's lives with their children Paul, Arthur and Nelly.

A source said recently: "Sam will be joined by her sister Billie in the new series of the 'Mummy Diaries'. There will be a Kardashians flavour to it this time - two sisters bringing up their broods and all the challenges and adventures they get up to together as a family. Billie has a great sense of humour and fans of 'The Mummy Diaries' saw her baby boy Arthur moments after being born and hilarious scenes of her trying to sleep train her daughter Nelly. Sam and Billie are extremely close and their onscreen chemistry is fantastic, the girls were only too happy to star together and make it more about the Faiers family as a whole."
