But now that she's done shooting Blood Ties (you know, the movie she gained all the weight for), it looks like she's on her way to slimming back down!

Mila Kunis was snapped running errands in the valley over the weekend, and the 28-year-old starlet rocked a sexy floral top and dark skinny jeans. After dropping down to 95 pounds to play a ballerina in 2010's The Black Swan, Mila packed on the pounds for the Guillaume Canet thriller, in which she plays a frumpy 1970s auto repair shop worker.

Kunis recently admitted to Harper's Bazaar that her body "has never been the same," since she dropped 20 pounds for Black Swan, adding, "My shape is different. When I got down to 95 pounds, I was muscles, like a little brick house, but skin and bones. When I gained it back, it went to completely different areas." So would she do it again? "I'm not going to say I'd look forward to it, but if an offer came along, I'd do it."

Mila Kunis and Robin Williams filmed The Angriest Man in Brooklyn today, and we're not entirely sure what the film is about (according to IMDb, the flick follows "a man who tries to determine what he will do in the final moments of his life"), but today's scene had the actors shooting in the Hudson River! Brrr...

In other Mila news, Now Magazine is reporting that the actress and beau Ashton Kutcher are looking to adopt a dog, but Britain's Closer Magazine is taking it one step further, claiming the two are trying to start a family! "They’ve been so happy since moving in, they’ve said they’ve discussed starting to try for a baby,” a source told the mag. “They don’t see the point in waiting when they’re so deeply in love and want the same thing.”

So what about Ashton's ex-wife, Demi Moore? “Mila knows she’s not always going to be liked by Demi, but she’s done nothing wrong,” the source added. “Now she and Ashton have decided to make a real go of things together, she’s never been happier.”

Mila Kunis sure is looking stern these days!

The 29-year-old actress appeared all business as she arrived onto the set of her new movie, The Angriest Man in Brooklyn. Someone put a smile on that face!

Mila has been in NYC recently to shoot the thriller which also stars Robin Williams and James Earl Jones. Maybe she's still feeling a bit bitter about her haunting elevator episode last week?

It has been said that exercise relieves tension, so hopefully some intense cycling did the trick!

Mila Kunis attended an LA area spin class today, and the Ted actress looked a little stressed on her way out. Cheer up girl!

It's totally normal that the brunette beauty opted to go makeup-free for her workout, but something about her face looks a little bloated, even though the rest of her body appears toned... are romantic dinners with boyfriend Ashton Kutcher causing her to pack on a couple pounds?

Given that she's one of Hollywood's hottest stars, the Oscar nominee was probably just having an off day from her beauty routine. We bet her Two and a Half Men beau prefers her au naturel anyway!

We're not quite sure what's going on with the Black Swan beauty, but we'll just chalk it up to a bad hair/face day!

Today Mila Kunis was spotted leaving the gym in the valley on Wednesday, and the 29-year-old starlet looked nothing like the sexy brunette we remember from That 70s Show. Speaking of rolls roles, it was just announced that Mila will be joining the cast of Paul Haggis's drama Third Person with James Franco and Casey Affleck.

The flick follows three interlocking love stories, and Liam Neeson and Olivia Wilde are also set to star. Wonder who Mila is going to be paired up with? Hopefully boyfriend Ashton Kutcher won't mind her getting busy with someone else on the big screen!

They're STILL trying to keep things on the DL, but we all know that they're dating, so what's the point?

Mila Kunis and Ashton Kutcher are back from their vacation in Bali, and the lovebirds had an early dinner at Casa Vega in Studio City on Sunday evening. Though they left the restaurant a few seconds apart, as soon as he hopped in their car, Ashton made sure to pop open the passenger door for his ladylove.

While they still haven't made any public appearances as a couple, on Saturday Mila was spotted visiting Ashton on the set of Two And A Half Men, so maybe she'll join him on the red carpet when it's time to promote the tenth season of the show? The premiere date is set for September 27, so he'll undoubtedly be making more appearances in the weeks to come!

Things are really heating up with these two!

Ashton Kutcher has reportedly whisked lady love Mila Kunis away on a romantic vacation to Bali, according to Page Six. Apparently the Jobs actor has taken the Ted actress to a five-star resort on Bali's southern peninsula, where suites include four poster beds, indoor bathtubs and ultra private pools.

The former That 70's Show co-stars are beginning to be more public with their romance, after enjoying low key dinner dates and motorcycle rides at the start of their courtship this spring.

"Ashton was Mila's first kiss while on That 70's Show , so they've always had a special bond. They started dating in the spring, and things have recently become more serious," a source divulged to the column.

Meanwhile, Kutcher's ex Demi Moore is moving on as well! The 49-year-old Striptease actress is dating New Zealand actor Martin Henderson.

We're glad these sweethearts are going public with their love!

Mila Kunis was all wet and sweaty after an intense workout in LA on Friday afternoon, but she still looked amazingly hot!

The Black Swan star has been dating former That 70s Show costar Ashton Kutcher, and we spotted the pair enjoying a romantic date together at the Duplex Restaurant in West Hollywood the pervious night, after they went "public" at his Jobs wrap party last weekend.

Despite their constant relationship denial, it seems like the adorable pair are definitely more than "just friends."
