The Factory Girl star is said to be planning a summer wedding with the 39-year-old actor, who first asked for Miller’s hand in marriage in August (07) by sending her a cryptic message in Welsh, his first language, which read: “Marry the Misfit.”

He proposed for a second time in December (07) at her 26th birthday party by hiding an engagement ring in a pile of gifts.

But it proved to be third time lucky for the Notting Hill star after Miller accepted his proposal earlier this month (Mar08).

And the one-year couple is reportedly keen to keep their forthcoming nuptials low-key.

A source tells British newspaper 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.

“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.”
Miller, who has previously called Ifans her soulmate, recently said, “I am in love - Rhys and I are the best of mates and life is going great.”

Sienna Miller is used to playing a gentle, doe-eyed love interest - but she sure is toughening up.

The 26-year-old began shooting her new Hollywood film GI Joe in Los Angeles yesterday, in which she plays the villainous Baroness - a femme fatale skilled in espionage.

She filmed a funeral scene yesterday, where she was seen carrying a folded American flag and spent the breaks between takes texting on her mobile.

The actress is rumoured to have gained 5lbs and has started an intensive fitness training in preparation for the role.

She has said: “I’ve started taking boxing lessons, and I’ve also had to learn how to fire guns with live ammunition.

“I’m a baddie, running around kicking everyone while wearing tight, thigh-high boots.

“I’m getting muscles everywhere.”

Sienna was the first star to sign up for the film, and she has since been joined by up and coming star Channing Tatum as well as Dennis Quaid.

Military action hero GI Joe started life as a Second World War comic strip and went on to become a popular series of toys in the US.

The film is set at the Brussels-based GIJOE - an acronym for the Global Integrated Joint Operating Entity - where a band of special operatives battle to defeat Cobra, an evil organsation headed by a Scottish arms dealer. It is expected to be released in August next year.

Next up, Sienna is scheduled to star alongside Sean Bean in the romantic comedy A Woman of No Importance.
