Star's mother is said to approve of her new love

Sienna Miller’s relationship with Rhys Ifans has got the seal of approval from her mother, says a friend of the couple.

Drama teacher Jo is said to have invited the Welsh actor over for dinner at her Fulham home last week, where ‘she treated him like one of the family’.

‘Sienna’s mother Jo adores Rhys and thinks she should make a commitment to him,’ the source tells the Sunday Express.

‘Jo can see that he makes Sienna really happy.’

And despite constantly denying that they are an item, the couple are now rumoured to be house hunting together.

‘Sienna and Rhys are looking for a cottage in Wales,’ says the insider. ‘They have agreed to put it in joint names – which is already a big commitment.’

It looks like things are getting pretty serious…
