Sienna MillerSienna Miller has reportedly finally agreed to marry boyfriend Rhys Ifans after he proposed for a third time.

Notting Hill star Rhys first asked last summer, then at her 26th birthday party in December but he only got the answer he wanted when he asked a third time at their London home last month.

A source told the Sunday Mirror: “Rhys has admitted he and Sienna are getting married.”

Everything is supposed to be hush-hush, but Rhys is over the moon and finding it hard to keep quiet… he can’t believe she finally said yes.”

According to the source, the couple are now planning a summer wedding but won’t be going for an extravagant ceremony: “Although Si and Rhys have a lot of famous friends, they will keep it low-key. They won’t be signing up to some magazine deal.”
