At the Billboard Awards in Las Vegas last night, the Glee guy asked if he could join the country singing trio.
But lead singer Charles Kelly wasn't too thrilled with the idea:
"We don't like to share the spotlight," he joked on the white carpet at the MGM Grand Sunday. "We've got enough dudes in the group!"
Despite Matthew's claim that his favorite thing to do in Vegas is "sleep" and go to the spa, he was out and about last night after presenting an award at show. He later attended the official Billboard afterparty at Tao.
Another guy letting his hair down this weekend was Joe Jonas. The 21-year-old hosted a bash at Tao on Saturday night and went to Rihanna's afterparty at Lavo, where the deejay introduced Joe on the mic to a packed house that included Jay-Z.
Way to up that street cred!
