I guess dating Ashton Kutcher makes you pretty popular, because Mila Kunis was swarmed by photographers when she left the gym in Beverly Hills yesterday!

Despite denying any romantic involvement with her former That 70s Show co-star, the lovebirds have gone out for romantic dinner dates, taken a trip and had several sleepovers since we first reported that they were an item less than two weeks ago.

And get this -- People has uncovered an interview from 1998 where Mila reveals that Ashton was her first kiss onscreen ... and in real life! Mila, who was just 14 at the time, told the mag, "I was like, 'Oh, he's so cute, it's the Calvin Klein model!' Then I was like, 'I have to kiss him?' I was so nervous and uncomfortable. I had the biggest crush on him. Ashton was so nice. He just made jokes and gave me funny little compliments. He made me laugh."

So what did Kutcher have to say about it? In 2001 he told the mag, "I'm the first guy she kissed? Oh my God, I had no idea! I'm so glad I didn't know that or it would've been too much pressure. I was so nervous. She acted so cool. She seemed as if she'd done it a thousand times. I was the one with butterflies in my stomach. I mean, here's this little girl and I have to kiss her. It was nerve-racking."

Hmm, so is she going to stick by her story that their relationship is strictly platonic?

X17online was the first to report that Ashton Kutcher and Mila Kunis are definitely an item!

The two spent a romantic weekend just north of Santa Barbara in the town of Carpinteria, according to People.

Ashton and his former That 70's Show costar enjoyed a sushi dinner, bought sunflowers and blueberries at a roadside fruit stand ... and spent lots of private time together says a source.

The source adds:

"He was so in love with her for a while when they worked together. He thought she was a goddess, was always talking about how beautiful she is. But she was with Macaulay [Culkin] for a lot of that time and also just generally gave off a not interested vibe."

Sounds delish! Reps for both stars have denied that the pair are an item.

But she's not leaving rumored beau Ashton Kutcher's house!

The actress hit the gym in Los Angeles today, and she covered up her makeup-free face when we snapped her heading back to her car. Mila recently wrapped production on Oz: The Great and Powerful, and she's currently voicing a character in Hell & Back, which is about "two best friends set out to rescue their pal after he's accidentally dragged to hell," according to IMDb. After that she'll be working on Blood Ties with Zoe Saldana, Marion Cotillard, Clive Owen and Billy Crudup, so it looks like she's trying to whip her hot bod back in shape for that one!

Ashton Kutcher and Mila Kunis have been spending more and more time together lately, and last night we spotted the former That 70's Show co-stars leaving Asanebo sushi in Studio City after a romantic dinner date!

The duo then returned to Ashton's massive Hollywood Hills mansion, and our photographer tells us they looked quite cozy when they dined together. "Ashton was touching Mila's hand and Mila was all dressed up," our lensman reveals. "She looked hot; this was definitely more than a dinner between friends -- this was a full-on date!"

These two may be friends with benefits, but will this romance last? Or is Mila just another rebound for the Two And A Half Men star?

Ashton Kutcher has rebounded (again) after the breakup of his marriage to Demi Moore -- this time, with his former That 70's Show co-star Mila Kunis!

X17 photographers have spotted the actors together on multiple occasions, recently. Ashton and Mila have even spent the night at each others' houses!

Today we saw the two furniture shopping and grabbing a sushi dinner together tonight at Asanebo in Studio city before they returned to Ashton's new mega-mansion in the Hollywood Hills.

Our photographer tells us the couple looked more than cozy together inside the restaurant: "Ashton was touching Mila's hand and Mila was all dressed up. She looked hot; this was definitely more than a dinner between friends -- this was a full-on date!"

Mila was wearing skin-tight skinny jeans and super-high heels, while Ashton was in his uniform -- a baseball cap and sweater. Ashton chauffeured, with Mila in the back seat.

Will Mila and Ashton last? Or is this just another rebound romance for Kutcher?

Looks like Mila Kunis needs an aspirin, stat!

The Black Swan star held her pretty head in her hands as she ran errands around Hollywood on Monday afternoon, and while she was dressed-down in sweats, we couldn't help but notice her drool-worthy "Miss Dior" bag -- Kunis is the spokes model for Christian Dior's new line, after all!

Recently, former Real Housewives of New York star Bethenney Frankle confessed that she's desperate to have the Oscar nominee star as herself in an adaptation of one of her books.

The novel centers on Faith Brightstone, and her journey to LA in pursuit of fame and fortune. "When I thought about the lead character, I thought about people like Mila Kunis," Frankel told the Associated Press. "Expect the unexpected. I think that Mila Kunis would be perfect."

Who wouldn't pay to see Miss Kunis in a movie with the title, Skinnydipping?

We're not sure if this is PMS bloat or a bad angle, but Black Swan hottie Mila Kunis definitely looks like she's put on a few pounds!

Over the weekend we spotted Mila leaving her workout in Beverly Hills, and after wrapping up production on Oz: The Great and Powerful and Ted, the only thing Mila has been working on is voicing her character on Family Guy. I guess it makes sense that she hasn't been as conscious about her body lately...

Dior

Mila Kunis is the fresh, new face for Dior's spring/summer 2012 campaign.

The Black Swan beauty replaces French actress Marion Cotillard who has represented the fashion line's handbags for the past year. Kunis said the following about landing the spot:

"I am absolutely thrilled to be working with Dior. The brand is iconic in so many ways. It defines fashion, elegance and sophistication."

Macaulay Culkin's ex is definitely a stunner!
