Ashton Kutcher and Mila Kunis showed off their young love as they packed on the PDA at a party in L.A.

Kutcher and Kunis were spotted spending sweet time together at the after party for the Oz the Great and Powerful premiere in Los Angeles on Wednesday.

The 29-year-old actress was dressed in a Dolce & Gabbana dress, which she wore to her latest flick’s premiere. Kunis paired the dress with a slouchy black bomber jacket.

Her 35-year-old beau was dressed more casually in a white sweater and baseball cap.

The loved up couple was seen at Lure Nightclub in Hollywood around 10:30 p.m. Wednesday night.

"They headed straight for the buffet, where they piled their plates with lemon garlic seared chicken breast and butternut squash ravioli," a source told US Weekly.

 As guests arrived, Kutcher remained at his seat as Kunis welcomed everyone into the group and made a point to chat with most people, People reports.

The lovebirds were showing some PDA as Kunis sitting on Kutcher’s lap and holding hands. They also shared kisses and hugged each other, and staring into each other’s eyes from time to time, according to People.

"Mila and Ashton kissed softly on the lips … [He] wrapped her in his arms ," the source said.

Before 12:30 a.m., the duo exited the event.

Ashton Kutcher and Mila Kunis are certainly qualified as one of the sexiest couples of Hollywood, but their Valentine’s Day may not be as sweet as fans imagine, as Kunis seems to be more or less indifferent about the romantic occasion.

 “I’ve never really put much emphasis on it,” Kunis said on “The Ellen DeGeneres Show” Wednesday.

“I’ve been single during Valentine’s Day, I’ve been in a relationship – either way, I’m fine with it.”

Regarding what she wishes to receive on the Valentine, Kunis pondered and eventually gave an answer, saying,
“I think something simple, sweet and meaningful is great.”

“I love flowers, so flowers are nice. Chocolates, who doesn’t like chocolates … super stereotypical, all day long. … I want the biggest bear, and I want like, a thousand roses. If we’re going to do it, we might as well do it full out.”
