Lea Michele dated Matthew Morrison.

The 27-year-old actress - who denied being romantically involved with her 'Glee' co-star in the past - has finally confessed that the pair dated in her new book 'Brunette Ambition'.
However, Lea - who was in a relationship with her late co-star Cory Monteith from late 2011 until he passed away form an alcohol and heroin overdose in July 2013 - insists she dated Matthew, 35, long before they began working together on the set of 'Glee'.

She wrote: ''When we shot the pilot [for 'Glee'], I met Cory Monteith, Kevin McHale, Amber Riley, and Chris Colfer for the first time. 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.''

Lea - who plays Rachel Berry on the hit FOX TV show - denied rumours she was involved with Matthew as they filmed the first series of 'Glee' in 2010, claiming the pair enjoyed a ''close'' friendship instead.

She said at the time: ''I've known Matt for years. He's been a friend of mine from New York. People are going to make things up. I think it's just because we really are so close.''

Addressing the same rumours, Matthew previously said: ''We were literally on set and I got a call from my publicist [about Lea], and [Lea] got a call a minute later and we looked at each other like, 'What the f--k?' It's so laughable.''
