Micah Alberti

Rumer Willis and Micah Alberti have parted ways.

"They decided it wasn't working," a source said.

Sad, but Willis, whose stepfather and mother, Ashton Kutcher and Demi Moore, have been under fire for relationship woes of their own, is bouncing back just fine.

IT'S OVER: Rumer Willis and Micah Alberti have called things off.

Saturday, she headed to Tao in Vegas, where she partied with Glee cast member Mark Salling and his pal Chord Overstreet, who appeared on the show as well.

"Rumer was bouncing around the club having a great time just dancing," says an onlooker. "Chord was flirtatious with Rumer. They clearly had a lot of fun."

Might that fun lead to something more serious? We'll have to wait and see.

Rumer Willis has gone public with her new boyfriend Micah Alberti (who we thought initially was Michael Alberti) at the premiere of her latest film.

He was Willis' date to the Los Angeles screening of the comedy The House Bunny, in which she plays a misfit university sorority girl.

The couple were first spotted together at LAX airport last week.

But who is this mysterious Micah Alberti fellow, exactly?

He is best known for his former role of James Martin on All My Children. He has also appeared on Smallville, CSI: Miami and other shows.

Micah Alberti is 24 and hails from the oddly-named town of Oregon, Wisconsin.

Here's hoping we see much more of this handsome fella going forward.

Remember when we said that Rumer Willis was spotted at LAX Airport with her alleged new boyfriend, Michael Alberti, a couple of days ago?

No? You don't keep up on Rumer rumors 24-7? Well, we got his name wrong. Apparently it's Micah Alberti. We apologize for the error.

The oddly-named and supposedly beautiful Rumer Willis - who just celebrated her 20th birthday - was spotted at Los Angeles International Airport with her alleged boyfriend du jour, Michael Alberti, over the weekend. Check it out ...

Michael Alberti and Rumer Willis prepare to fly somewhere.

We're not entirely sure where they were headed, or who Michael Alberti is, but he seems like a handsome fellow, don't you think?

Guess this means she and 90210 star Ryan Eggold are a thing of the past. It's getting hard to keep track of Rumer Willis boy toys.
