Rhys Ifans' mother confirms he is engaged to Sienna Miller

Rhys Ifans' mother has confirmed reports the actor is engaged to girlfriend Sienna Miller.

The couple are now reportedly planning a summer wedding after the 'Factory Girl' star accepted Ifans' third proposal earlier this month.

Rhys, 39, first proposed to Sienna in August last year by sending her a cryptic message in Welsh, which read: "Marry the Misfit."

The 'Human Nature' star then proposed for a second time in December at Sienna's 26th birthday party by hiding an engagement ring in a pile of gifts.

And on Rhys' third attempt -- just a few weeks ago -- Miller, 26, agreed to take his hand in marriage.

Rhys' mom Beti-Wyn Evans says she is delighted at the prospect of having the young Hollywood star as her daughter-in-law.

She said: "They adore each other and I am so pleased for them. They make a fantastic couple. We think she is lovely, absolutely fantastic."

Beti-Wyn also hinted that the newly engaged pair are planning to re-located to Wales -- so Ifans can be closer to his family.
