Sienna Miller Swimsuit Body: Sienna Shares Life With Tom Sturridge, Their Daughter, & Bear-Sized Dog [Photos]

Sienna Miller flaunted her swimsuit body. On vacation with boyfriend Tom Sturridge, Sienna chose an itsy-bitsy bikini for her visit to Spain, reported People.

At 33, Miller is the proud mom of 2-year-old Marlow, her daughter with Tom. But that swimsuit physique makes it clear that she knows how to shed the post-pregnancy pounds.

Famed for her role in American Sniper, Sienna is part of the Cannes International Film Festival jury. She also is set to star in a film directed by Brad Pitt. In The Lost City of Z, Miller will work with Robert Pattinson and Charlie Hunnam.

Marlowe was born in July 2012, and Miller admitted that her time to exercise has definitely been cut short, reported Us Weekly.

So in order to slip sleekly back into that swimsuit, Sienna has hired a personal trainer. Miller is particularly fond of yoga for restoring her pre-baby body.

“It’s hard, because there’s just no structure to my day. With a child and my job, I have enough to do, I can’t always make it to the gym,” admitted the actress. “I do try to do something with my trainer Efua Baker every now and again, preferably yoga, but that’s not enough of course.”

However, as the Inquisitr reported, Alec Baldwin’s wife, Hilaria, swears by yoga for restoring her own pre-baby body. Hilaria is a yoga instructor, correspondent for Extra, and co-founder of Yoga Vida.

Her favorite hashtags include #yogapostureoftheday and #hilariaypd, and Hilaria loves to pose in places ranging from before her refrigerator to on the street.

For Sienna, however, the joys of motherhood overwhelms any worries about losing all of her post-pregnancy pounds, reported Vogue.

“I was overwhelmed by how normal [motherhood] felt. It was like, ‘There you are— that’s what I have been missing.’ Like we’re both in on something only we know. An amazing sense of being complicit with a little being.”

Miller also adores Marlowe’s papa. Tom and Sienna have been dating since 2011.

“[Sturridge is a] grounded, intelligent, kind, and intact person,” she said. “That’s amazing to be around. That’s the father of my child. There’s no drama.”

As for Sienna’s daily life, she views it as normal.

“Very normal, very kind of still,” Miller summed up. “We go to the country. I like to cook and go to Whole Foods. I have a dog [Newfoundland]—not a dog but a bear, who when I walk pulls me over flat on my face into the mud. My baby pukes on me. It’s life. It’s very much a normal life.”
