Fashion police Kelly Osbourne cried after her first bikini shoot.

The TV star - who has dropped to a US size 2 following her appearance on last year’s Dancing With The Stars - admitted she was so “thrilled” by her svelte figure, she was reduced to tears.

“I just shot the cover of Shape magazine, which as such an incredible experience. I have never worn a bikini in my life before yesterday. I never even thought of wearing one! I cried when I saw the picture. Everyone that was there, we all just burst into tears. It was a thrilling experience.”

The newly-single blonde - who ended her engagement with Luke Worrall in July amid claims the model had cheated on her - explained while she finds sticking to her new exercise regime easy, she still can’t believe sample sizes fit her.

“I just commit to half an hour a day. It doesn’t seem overwhelming and I can handle that. I do half an hour on the treadmill and when I feel like doing more, I’ll do a few sit-ups and some weights. Now every designer will send me anything that I want, and I can’t believe that I am in this situation. I opened up all of these zip bags last night from Marchesa - off the runway -  and I can’t believe that it fits me.”
