Sienna Miller's Birthday Engagement

Sienna Miller and Rhys Ifans were spotted over the weekend leaving the Wolseley Restaurant after having lunch in Mayfair.

It is reported that Sienna and the Welsh boyfriend Rhys get engaged on Siennaís birthday after spending Christmas together in Wales.

Sienna recently celebrated her 26th birthday where Rhys proposed her. A source told Britainís Sun newspaper that before the birthday proposal Rhys had collected 10 presents for Sienna of varying shapes, sizes and prices. They were all part of a plan for a romantic night in with a mountain of presents.

The insider added: "He is keeping tight-lipped on a proposal but hinted to he has had a Welsh designer craft a special ring for her, which can only mean one thing."

A special ring makes a special birthday, doesn't it?
