London, Aug 21 - Mothers-in-law can put a strain on a relationship but Robbie Williams has gone ahead and invited girlfriend Ayda Field's mom Gwen to move in with them in his mansion.

With Williams moving to Britain full-time with his girlfriend ahead of the new album release, he's keen for Gwen to come too. The singer feels it's good for American Ayda to have her mum around especially if he's going to be busy promoting 'Reality Killed The Video Star'.

'Robbie's new house is massive and it would be a lonely place to rattle about in on your own. But Ayda and Gwen will have a lot of fun together. There are tennis courts and a gym and some nice countryside. Plus there is completely separate accommodation so Gwen can have her privacy,' thesun.
