Kelly Osbourne works out with her mom

Kelly Osbourne and her mother Sharon work out together. The TV star — who lost a considerable amount of weight during and following her appearance on last year’s season’s of Dancing with the Stars — says her mother is so impressed with her figure she has started exercising with her and her personal trainer.

“Mom’s started to work out with me and my trainer, Sarah Hagaman,” Kelly said in her column for Britain’s Closer magazine. “She loves it.”

The 25-year-old beauty admits it was hard work losing so much weight, but she is glad she did it the right way by eating healthily and exercising.

“My weight loss has been healthy and gradual. I haven’t gone to extremes — it’s just been down to smart eating and regular exercise,” she said.

However, Kelly’s new enviable figure isn’t just down to hard work and discipline — control underwear Spanx is her secret weapon to look good.

“I love Spanx – not so much for sucking you in, but more for smoothing you out,” she said. “There’s nothing I hate more than being able to see someone’s belly button through their dress.”
