It’s turning out to be quite the holiday season for Sienna Miller, as the actress recently celebrated her 26th birthday by reportedly getting engaged to Welsh boyfriend Rhys Ifans.

The couple, who were spotted over the weekend leaving the Wolseley Restaurant after having lunch in Mayfair, “officially got engaged on Sienna’s birthday after spending Christmas together in Wales.”

Before the birthday proposal, a source told Britain’s Sun newspaper of Rhys’ plan: “He’s collected 10 presents for Sienna of varying shapes, sizes and prices. They are 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.”
