The 36-year-old rugby star - who is dating his former 'Strictly Come Dancing' partner Kristina Rihanoff, 37 - and Abby Cohen are in the middle of a bitter divorce but after struggling to sell their £1.75 million home, Ben has reportedly moved back in to cut costs.

A source told The Sun newspaper: "Ben thought he'd be able to sell the house and rent somewhere for Abby and the kids before their divorce went through.

"But there's been little interest and the cost of the mortgage and renting has become very expensive.

"He gets to see his kids more, but it has been really awkward for him and Abby."

It's not surprising things are awkward as Abby recently revealed she believes Ben cheated on her with Kristina.

The professional dancer - who has been nicknamed the Siberian Siren - insisted she and Ben did not get together until after his split from Abby, but Abby believes their relationship began when they were partnered together on the show in 2013.

Abby said: "I feel like he deceived me on every level you can imagine.

"My husband, who I was with for 23 years, unconditionally loved and was completely loyal to in every respect, has left me for a f***ing Russian dancer."

Rumours of an affair between Ben and Kristina first began circulating when they were competing on the BBC One dance contest.

But the pair claim they didn't get together until earlier this year, following Ben's split from Abby in September 2014.

Abby has twin daughters Harriette and Isabelle with Ben and is now "concentrating" on her children as well as her photography business.
