Mila Kunis kept her promise and made one Marine hero a very happy man Friday night. As the Friends with Benefits star said she would, Kunis attended the Marine Corps Ball on the arm of Sgt. Scott Moore.

The event, celebrating the 236th birthday of the Marine Corps, was held at the Greenville, NC Convention Center.

As RadarOnline.com previously reported, Sgt. Moore, in full combat gear, asked the actress to be his date via a video he posted on YouTube.

Mila accepted and Tweeted about how "happy" she was to be going.

It was after her acceptance that another Marine, Cpl. Kelsey De Santis, asked Justin Timberlake to be her date at a Marine gala held last weekend in Richmond, Virginia. He was also an actor of his word, and attended.

Sgt. Moore -- "you can call me Scotty" he told Mila on his video -- is a member of the 3rd Battalion, 2nd Marines, a unit that lost seven of its men during its recent deployment in Afghanistan.

Marine spokesman Sgt. Scott Sasser said Mila and Moore enjoyed the night.  “It’s good that she got to come on a date with a Marine,” he said.

Justin’s brought sexy back into his life!

Justin Timberlake and Jessica Biel were snapped taking a leisurely bike ride together in Toronto over the weekend and RadarOnline.com has exclusively learned the former exes are romantically back together again.

“They decided they wanted to be together and they’re happy again,” a source close to the couple told RadarOnline.com.

She's an A-list stunner who makes her living playing the girl every guy wants.

Strangely, actress Mila Kunis says she's "not good at sexy."

Kunis, 28, told The Times newspaper that despite lacking seduction skills (her opinion, not ours!), she still gives it her all when performing in steamy scenes, as she’s done in Black Swan and Forgetting Sarah Marshall.

Watch out world, Mila Kunis doesn't let anyone mess with Justin Timberlake!

The gorgeous star of Friends With Benefits jumped to her co-star's defense at a press conference in Moscow, in her native Russian!

When a Russian reporter asked Timberlake why he's focusing on his movie career instead of his singing career Mila leapt to his defense.

Sorry guys, that super sexy butt you see in the movie Friends With Benefits doesn’t belong to Mila Kunis.

The 27-year-old star of the upcoming film told Ryan Seacrest that she just wasn’t ready to show off her butt on film.

Actress Mila Kunis might headline A-list films, but when she's looking for entertainment, nothing scratches her itch like Snooki.

Kunis, a self-described reality TV junkie, appeared on Jimmy Fallon Monday, and Fallon (also an admitted reality TV buff) asked her what she watches, specifically.

"What don't I watch?" the gorgeous 27-year-old ex of Macaulay Culkin told Fallon. "Apparently I love New Jersey, because I watch Jerseylicious and Jersey Shore.”

Justin Timberlake made Corporal Kelsey DeSantis' day on Friday.  JT said "yes," he will go with her to the Marine Corps Ball in Washington, D.C. this November.

DeSantis' YouTube invite to JT followed a similar shout-out to his Friends with Benefits costar Mila Kunis by Marine Sgt. Scott Moore. He invited the actress to the North Carolina Marine Corps Ball, and she accepted.

That inspired DeSantis to ask Timberlake to escort her to her dance, and she told him if he didn't she'd Cry Me A River, a reference to one of Timberlake's biggest hits.

"I'll tell you what, I accept," Justin announced during a Friends with Benefits promo event.  Justin added that no one ever asks him out.  "If my schedule works out to do it, I'd love to do it.  It's an honor."

Justin Timberlake sang it best: What goes around comes all the way back around.

Just days after he persuaded his Friends With Benefits co-star Mila Kunis into accepting a date with a marine that asked her to a Marine Corps Ball via YouTube, the Sexy Back singer has been asked out himself by a female marine named Cpl. Kelsey De Santis.

Mila Kunis tweeted she’s “so happy to be going to the Marine corps Ball!” after she accepted a date offer via YouTube from Sgt. Scott Moore, a marine stationed in Musa Qala, Afghanistan as part of the 3rd Battalion 2nd Marines.

Sgt. Moore posted a 19-second video to YouTube (it’s already got more than 700K views), asking Kunis (Black Swan, Forgetting Sarah Marshall) to be his date at a Marine Corps Ball in Greenville, North Carolina this November.
