Glee star Matthew Morrison has taken a damning swipe at former flame Kelly Brook, insisting she's "not the brightest bulb".

Actor Matthew, 33, was linked to the buxom beauty in 2010 after the pair met whilst Kelly was visiting LA.

The Glee star has now confirmed there was a short-lived fling - but suggests there's not much behind Kelly's eyes.

He told The Mirror: "I once went out with a Brit. I didn't realise she was such tabloid fodder. It was Kelly Brook... she's not exactly the brightest bulb. We only went on one date."

Matthew dated Kelly, 32, shortly after she split from her rugby hunk ex Danny Cipriani and at the time their romance was believed to be going from strength to strength.

Matthew initially denied they were an item, telling OK! magazine at the time: "There's nothing going on with me and Kelly. She's lovely and I've known her for a while - we met when she was over in LA."

But the former lovebirds quickly moved on from each other - Kelly is now dating former rugby ace Thom Evans while Matthew is seeing model Renee Puente and concentrating on his career.

Yet frustrated Matthew admits his work life isn't going as well as he'd hoped.

Discussing Glee, he confessed: "It's not ending any time soon. Once they have you, they trap you. I'm tied in to seven years - I signed up to seven years and I cannot get out of it. I have a really good lawyer but there's nothing we can do - I've had offers recently for a few really cool movies but had to turn them down. It's so frustrating.

"None of us realised when we signed up it'd turn into this - we thought it was just a show about kids singing and dancing. But I've done three years now, so I have another four to go - I literally cannot get out of it. It's a great show, it provided me with my big break, but what can I do?"
