Here's what an insider has said about Rumer's reaction to her split with Alberti:
“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.”
More on post-breakup Rumer from an eyewitness:
"She spent a few minutes talking to Chord Overstreet, the new cast member on Glee. They just chatted a few minutes and went their separate ways."
Going out and trying to have fun and cheer up is a healthy way to deal with this, Rumer! We're proud of you, bb!
