The `Angels` singer - who married his long-term love Ayda Field on 07.08.10 - has invited her mother Gwen to live with them after she struggled to make her mortgage payments.

Gwen will live in a cottage on the grounds of the singer`s $12 million Los Angeles estate.

A source told The Sun newspaper: "Gwen has been struggling with repayments on her home over recent months.

"She`s remortgaged the property a number of times and now owes more than the value of the house.

Kind-hearted Robbie, 36, quickly stepped in to help and is happy for her to live their as long as she wants.

The source added: "Rob couldn`t face seeing her struggle any longer, so he invited her to move in. Gwen had been reluctant to accept his help, but realises she has to."

Robbie - who moved back to Los Angeles from Britain because he missed the sunny weather - gets on well with Gwen after they bonded over their love of gambling.

A source previously said: "Robbie has really hit it off with Gwen. One of his hobbies is playing poker with a small group of pals. Gwen has joined in a few times, and on a couple of occasions, Robbie and Gwen have carried on playing until the small hours after everyone else went to bed."
