Sienna Miller held a baby shower in London on Sunday.

The actress and rumored fiance Tom Sturridge were seen leaving the shower with a friend, who carried boxes which appeared to house cakes and balloons for her baby, due later this summer.

Sienna wore a flowing dress and sandals and witnesses say she had a "pregnant mother's glow" about her as she smiled as she left the party. The couple had just flown back from the Cannes film festival in France, where Tom had been promoting his latest film On The Road.

In April, sienna spoke to Vogue magazine about her pregnancy, saying, "I'm feeling fine. It's all progressing nicely and it's very exciting. I'm in my second trimester, so I'm 'I-can-talk-about-it' pregnant."

Earlier in her pregnancy, the Factory Girl star said she had taken up yoga to help her relax, as she hates working out:

"I have been trying to do some pregnancy yoga as I'm definitely not a gym person. My mum started up one of the first yoga schools in London in the 70s, so I should probably use her expertise as I have really bad posture. But I think I'd probably kill her if she tried to tell me to sit up straight."
