Sienna Miller is reportedly considering marrying boyfriend Rhys Ifans after he proposed to her in the form of song.

Rhys is said to have written a poem entitled “Marry This Misfit” and sang it for the Factory Girl star while strumming his guitar - but Sienna didn’t get the message at first.

A source told the Mirror: “She fell about laughing, but soon realised Rhys was serious. While she didn’t give him an answer straight away, she’s since been thinking about it more and more.”

“After telling people about Rhys’s strange proposal, Sienna’s been very coy about what her answer was. She’s been fudging the issue with mates and lots of people are starting to think that she may have even said yes.”

Whether Sienna accepts this current proposal or not, the source added that the couple definitely making long term plans and are considering buying a holiday cottage in Rhys’ native Wales together: “They want to get out of the rat race for quiet weekends and think Wales is perfect.”
