She wore a colourful Mary Katrantzou dress, teamed with Jimmy Choo Shoes.

The 31-year-old's face looked noticeably thinner- though she was still as pretty as ever, with her blonde hair falling in loose curls.

She tweeted a picture of her outfit as left for the awards, writing: 'On my way to the Glamour Awards wearing Mary Katrantzou & Jimmy Choo Shoes...'

The singer has blamed her strenuous Dancing With The Stars regime for her drastic weight loss.

What happened? Both Katherine and Myleene Klass- who also showed up looking very slim- used to be curvy girls

She confessed to The Sun that she's not enjoying the thin frame it's given her.

'I prefer being curvy and so feel like I am a little on the thin side at the moment,' she said.

'But on one day I eat pizza, chocolate cake, ice cream, two enormous salads along with a side of chips and it is not making any difference because of the training,' she continued.

On the plus side, Katherine added that the show did help her to get over her split from fiance Gethin Jones.

She said: 'This show has definitely given me a reason to laugh and just have fun doing something new... I felt I needed something like that.'

Jenkins has refused to be downbeat since losing in the final of Dancing With the Stars on May 22nd to American football player Donald Driver.
