Lea Michele once dated Matthew Morrison

Lea Michele has revealed that she once dated her Glee co-star Matthew Morrison before they signed on the TV musical.In her new book, Brunette Ambition, Michele says she briefly dated during their pre-Glee days, reported a magazine.

Michele, who lost her boyfriend and `Glee` co-star Cory Monteith to drug overdose, has denied a love connection with Morrison previously. The 27-year-old actress/singer admits she and Morrison, 35, actually did date -- albeit briefly and before `Glee`. "When we shot the pilot, I met Cory Monteith, Kevin McHale, Amber Riley, and Chris Colfer for the first time," Michele writes. "I had worked on Broadway with Jenna Ushkowitz and Matthew Morrison before. Matt had been a friend of mine for years, and in fact we`d actually dated back in the day for a Broadway beat."
