Rumer Willis and her actor boyfriend Micah Alberti have split. “They decided it wasn’t working,” a source close to the couple tells PEOPLE. “They’re moving on.”

Even though Demi Moore’s daughter was upset about the breakup, she headed to Tao in Las Vegas with some friends.

She was spotted out with ‘Glee”s Mark Salling and his pal Chord Overstreet, whom Willis reportedly flirted with all evening.

“Rumer was bouncing around the club having a great time just dancing … Chord was flirtatious with Rumer,” claims the source. “They had a lot of fun.”
