Matthew Morrison attended Elton John's concert, held to benefit gay marriage, yesterday in Hollywood. Glee star Matthew enjoyed the evening of music during a break from working on his own solo album. It was his latest night out on the town following his series's big night at Sunday's Golden Globes. The hit show won't return to the airwaves until next month, but it's already promising a star-powered season ahead. Anne Hathaway is the latest celebrity to sign on for a cameo, and the cast also plans to welcome Gwyneth Paltrow back again.
