Glee cheerleader Dianna Agron ditches her good girl image for sexy new shoot as she reveals gruelling tour schedule

She's usually seen in a cheerleader's outfit or cute summer dresses.

But Glee's Dianna Agron has ditched the girl next door image, striking raunchy poses that would make her schoolgirl character Quinn Fabray blush.

The 25-year-old can be seen in US fashion magazine Flaunt wearing a lace and sequinned Dolce & Gabbana bodysuit while clinging to a velvet curtain the same colour as her red lipstick.

Dianna, who recently split from her actor boyfriend Alex Pettyfer, said it had been hard work on the road during the Glee Live Tour around America and the UK over the past two months.

'It’s difficult work being part of something so widespread and global, for sure,' she said.

'The constant flights, the dizzying two shows-a-day schedule, the autographs, the interviews.

'But at the end of the day, when the reward is changing people’s perspective of what’s normal, and giving a voice to a part of America that still needs one, you almost never want to go to sleep.

'I’m the happiest that I’ve ever been. Ever. High school, middle school—I’ve loved every part of getting older and growing, but I definitely think that this is the most I’ve ever felt like myself and that I’m being treated like who I feel I am.'

She said most of the time fans recorded the show on their phones or took photos.

'I think it’s so hard, because people are so joyous in the moment, and want to be able to look back on it or share it with their friends, but you’ll see that more often than not, they’re watching the concert through the recording device.

'To me, that’s putting yourself back in front of the TV. You are part of it; you feel the energy. You’ll never see or feel that from a video, ever.'

Dianna, who appeared on People magazine's Most Beautiful list last year, recently celebrated her 25th birthday by cutting her blonde locks short.

She explained: 'It’s almost like putting on the glasses and all of a sudden you’re smarter.

'It’s a very interesting and lovely observation that I keep having of how people treat me now that my hair’s different.'

There has been no word on whether Dianna will return to William McKinley High after the third season, which premiers on September 20.

But she is certainly not short of work.

She recently starred in the big-budget I Am Number Four during which she started a relationship with co-star Pettyfer.

The couple split in February amid reports she was 'terrified' of him after a threatening phone call.

She has also written screenplays and sat in the director's seat for an indie music video.

She has had bit parts on CSI: New York and Heroes and since Glee, sat on Oprah’s couch and been a guest at the White House
