Dianna Agron has had a nose job.

The 'Glee' actress - who plays cheerleader Quinn Fabray in the musical comedy drama - confessed she had her nose fixed after breaking it twice, once after getting caught up in the middle of an argument at a high school party and again years later.

She told chat show host David Letterman: "The first time I didn't go to the doctor because I didn't want to tell my mom what had happened and she would never let me out of the house.

"I couldn't get it fixed because we were in the middle of doing this concert tour and we were filming. We had a day off and I met up with some of my friends and we were dancing. And again, there was another Collision of sorts - I must be turning too quickly, people don't see me coming or something - but it's fixed now!"

Dianna, 25, recently cut her signature blonde locks short and while she is has already altered the style several times, she much prefers her new cropped look to her old long tresses.

She said: "I've probably cut and trimmed it six times and it's changing slightly every time but I love it.

"I'd been dying to cut my hair for so long."
