David Arquette is back on the dating scene!

Courteney Cox's ex has called it quits with his girlfriend of five months, Christina McLarty.

Arquette, 40, Tweeted, "Sadly I'm single again. A long distance relationship proved to be too difficult."

The Scream 4 actor and the Entertainment Tonight reporter began dating in summer 2011.

Arquette separated from his wife Courteney Cox in 2010.

The two are the parents to 7-year-old daughter Coco.

David Arquette just can't quit the cancer sticks!

The Scream star donned an all-grey ensemble to match the dreary LA weather as he enjoyed a solo smoke in Beverly Hills, on Monday afternoon.

While Arquette has been spotted getting cozy with multiple women since his split with Courteney Cox, the Cougar Town star recently admitted she hasn’t had any action since their separation!

The former Friends star recently revealed on Howard Stern’s radio show, "I’m just not ready. I’m not saying I’m not ready to have a makeout session, I’m just not ready to – I don’t know. I’m not lying. … I’ve not had a man since David."

Is there still a chance for reconciliation?

Courteney Cox and David Arquette are back together, but it's only for a TV role on Cougar Town.

Arquette will be guest starring on the hit abc sitcom ... a show that both he and Cox executive produce.

The 40-year-old actor will play a hotel concierge on the show's season 3 finale episode.

Cox and Arquette split back in October 2010 after being married for 11 years.

The couple met while filming the horror movie Scream in 1996.

Arquette, who appeared on last season's Dancing with The Stars, is now dating Entertainment Tonight reporter Christina McLarty.

We haven't seen David Arquette this happy in awhile! The actor's younger girlfriend Christina McLarty, a reporter for Entertainment Tonight, must have something to do with it.

The duo, who have been dating since last summer, posed together for the cameras at the Opening Night Preview Benefit for the LA Art Show. Great to see the Scream actor is sticking with his sobriety.

Is it just us or does Ms. McLarty kind of resemble David's ex Courteney Cox? He definitely has a type.

Let's hope these two go the distance!

David Arquette has been sober for one year, and the Scream actor is ready to party ... minus the alcohol, of course!

Coco's dad was all smiles while he hit up Mr. Chow in Hollywood with his ex Courteney Cox. Great to see that despite the split, these two former lovebirds are still great friends! Just recently on New Year's Day, Courteney and David spent the day as a family with their daughter.

Although Mr. Arquette has been dating Entertainment Tonight's Christina McLarty, his new ladylove was a no-show.

Great to see Courteney Cox and David Arquette are the best of friends despite their split. Daughter Coco seems to be loving the fact that she gets to spend the first day of 2012 with both her parents!

Although David seemed a bit shy while out for a stroll with his family, Courteney and Coco didn't seem to mind all the attention. David's new flame Christina McLarty was nowhere in sight, but we have a feeling he spent New Year's Eve with his sexy new lady!

We're lovin' Coco's stylish black boots and Serendipity 3 shirt. Looks like these three are off to a great start for the new year.

He may be wearing track pants and a Dodgers jersey, but David Arquette made sure to dress up his relaxed ensemble with a plaid dinner jacket, for a lunch date with new girlfriend Christina McLarty, in Hollywood on Tuesday.

The former Dancing with the Stars contestant was actually dressed in gym wear for a reason -- he's still taking dancing lessons from former partner Kym Johnson!

Twitter

Arquette posted a Twitpic earlier in the day, before meeting up with his ladylove for lunch, with the caption: "Guess who I had a dance lesson with @kym_johnson - It was so much fun to dance with you again."

Too bad Dave can't return next season!




It must be serious! David Arquette introduced his new girlfriend Christina McLarty to daughter Coco months ago and the trio already looks like a family!

The group lunched at a Malibu park Saturday and our photographer tells us: "They all looked so relaxed and happy. Coco seems to have really taken to Christina. The two girls were lunching and playing around together. The seem like good friends."

Arquette and McLarty were first spotted together at Comic Con in San Diego in late July and David told Howard Stern during a radio interview in late September, McLarty is "adorable." According to Arquette, the two met at a "boat party."

Arquette has been separated from wife Courteney Cox for just over a year, though neither has yet filed for divorce. Still, if things continue to be serious with McLarty, perhaps David will want to make the break with Cox official. McLarty ended her marriage to Girls Gone Wild founder Joe Francis in 2010, after only two months with the notorious bad boy. Maybe she's ready to settle down with someone a little more stable now?
