It’s always cool when celebs are doing shows and they bring out “FRIENDS” in the industry. Even better, the fact that technology is around to share these cool performances. Pink was in Los Angeles last week and one of her fell musicians came out on stage with her and they did a duet. Gwen Stefani got on stage and the 2 ladies covered No Doubt’s 1995 song “JUST A GIRL”. Thanks to social media, we’re ALL able to get a look. Check out the footage HERE!
