Details of the split are unclear, but Life & Style magazine reports Rumer and Micah Alberti are no longer a couple.
A source tells the publication, "Rumer is very upset. She went to Las Vegas this past weekend with a few friends to try to cheer up and have fun, but she's very sensitive about the breakup."
XBox Kinect 'Project Natal' Premiere Red Carpet Photos
Ahh, remember the days of tangled up video game controllers and the millions of minutes of game play you lost because of such horrid entanglements? Yes, this is a problem we all have suffered from, like an empty jar of peanut butter. But it looks like this issue (the knotted controller cords, not the empty peanut butter jar) is finally behind us because Kinect for XBox 360 came out with a new console that doesn't even use controllers! All users have to do is make gestures or speak what they want their little men and women characters to do! But Kinect can also be used by people other than gamers (they DO exist). In any case, here's hoping Mario and Luigi are obedient little creatures.
And to celebrate the release of such innovative technology, Christina Hendricks, Rosario Dawson, Ryan Phillippe, and Rumer Willis all showed up at the premiere of "Project Natal" in Los Angeles last night. Lucky for them, they all probably walked away with systems of their own. Whether they stayed up all night talking to their televisions or commanding video game creatures is debatable. It's certainly what I would have done.

Demi Moore's actress daughter, 21, reportedly had her eye on the two-bedroom, three-bathroom starter home in Los Angeles but couldn't afford to buy the property on her own.
So Kutcher, who wed Moore in 2005, came to the rescue and wrote her a big cheque, reports the National Enquirer.
According to documents, obtained by the tabloid, the house deed lists Kutcher and Willis each owning 50 per cent of the property, with the actor listed under his birth name, Christopher.
The Los Angeles home is in the same neighbourhood as the home Borat star Sacha Baron Cohen shares with his partner Isla Fisher.
Demi Moore and Bruce Willis were rumoured to have been celebrating after their 21-year-old daughter accepted a marriage proposal from her longtime boyfriend, model Micah Alberti.
Rumer and Alberti were allegedly spotted shopping for wedding bands and preparing to hold their nuptials in June (10) - but a spokesperson has dismissed the stories.
A spokesperson for Rumer tells GossipCop.com the report is "not true," adding, "She is not engaged."
The 21 year old actress has accepted longtime boyfriend Micah Alberti's marriage proposal, according to PerezHilton.com.
Willis has been dating the model and actor since the summer of 2008, and the pair has been spotted shopping for an engagement ring.
A source tells the website, "I know they already have gone ring-shopping and are debating where to (get married)."
A representative for Willis had yet to respond to requests for a comment as WENN went to press.
The actress was partying at the Chateau Marmont hotel in Los Angeles with her husband Ashton Kutcher and her 21-year-old daughter, when Moore spotted a pole and began showing off the tricks she learned in the 1996 film.
But the star didn't hog the spotlight - she brought Rumer, whose dad is Moore's ex-husband Bruce Willis, to the stage and taught her how to copy her sexy moves, in front of fellow revellers Leonardo DiCaprio and Jennifer Aniston.
A source tells U.S. magazine Life & Style, "Everyone was cheering, and Leo gave Ashton a high-five."
Actress ALFRE WOODARD's daughter, MAVIS SPENCER, has been selected as Miss Golden Globe for the Golden Globe Awards in January (10). The 18-year-old model and showjumper has a big 2010 planned - she has also been accepted to study at Columbia University. Previous Miss Golden Globes have included Demi Moore and Bruce Willis' daughter Rumer Willis, Laura Dern and Melanie Griffith.
"Probably when I was little and I was on the set of DIE HARD, and I went into the make-up trailer and got a black eye or something and was like, 'Sweet. This is what I want to do!'" BRUCE WILLIS' daughter RUMER was bitten by the acting bug watching her dad make movies.
RUMER WILLIS is baking her way through America's chat show circuit - after presenting Jimmy Kimmel with a coconut banana-cream pie she had cooked up before his late-night show last week (11Sep09), the actress daughter of Demi Moore and Bruce Willis handed ELLEN DeGENERES a vegan strawberry pie during a guest spot on her show, which aired on Monday (14Sep09).
