Sienna Miller 'so excited' about her pregnancy

London, Mar 8 (ANI): Sienna Miller, who has done her best to keep her pregnancy under wraps, has now opened up about expecting her first child with beau Tom Sturridge.

The 30-year-old actress, who gave the interview as she posed for a chic new shoot in the April issue of British Vogue magazine, also revealed that she is very excited about starting a family.

The 'factory Girl' star is seen wearing a plunging pale pink gown while holding up a wreath of flowers which spell her name in the summery photographs taken by Ryan McGinley.

"I'm feeling fine. It's all progressing nicely and it's very exciting. It's nice to start a new decade," the Daily Mail quoted her as saying.

However, she also added that while she is looking forward to welcoming her first child into the world, she doesn't want to talk too much about the pregnancy because she wants to keep her life as private as possible.

"I'm in my second trimester, so I'm I-can-talk-about-it pregnant, even though I'm under strict instructions not to say anything as it would completely defeat the point of everything I've tried to achieve in the last eight years," she said.

Miller began dating in the 26-year-old actor mid 2011 shortly after her split from fiance Jude Law.

It is now believed that they are engaged, although the actress has yet to comment on the rumours. (ANI)
