Gwen Stefani left boyfriend Blake Shelton at home to help jewelry designer friend Jen Meyer celebrate her collaboration with Barneys New York last night in LA, and the singer clearly had a blast with Jennifer Aniston and there rest of her famous friends. By the looks of it, you would never know that this is a woman who has gone through some pretty significant heartbreak this past year!

The No Doubt front woman might be moving on with the country superstar, but she still has a lot of mixed feelings about her marriage to Gavin Rossdale ending. "I wish it didn't happen. I wish this... that all this wasn't happening, but at the same time, I feel like it was part of my life journey," she confessed during a radio interview with The Tommy Show.

"At the same time, there are lots of good things, and I do get to have a second chance, and I have a lot of joy right now," she added. A hot new beau certainly helps to lift your spirit!
