The 26-year-old television personality shot to fame as a teenager alongside mother Sharon, father Ozzy and younger brother Jack, in the hugely popular reality series The Osbournes.
Since the programme ended in 2005 Kelly has gone on to display her charismatic personality in a variety of acting and presenting roles, and the star believes 2011 will be an even more successful year for her career.
Kelly also plans to maintain her healthy lifestyle after wowing the public with her impressive weight loss.
“My main resolution is to stick to my new gym routine, and maintain the momentum in my career – things can only get better!” The star told Closer magazine when asked for her New Year’s hopes.
Kelly first began losing weight when she appeared as a contestant on television ballroom dancing competition Dancing with the Stars in 2009. She worked hard at maintaining her slender frame, and has recently expressed how proud she feels of her body and the decision to alter her party lifestyle.
“I'm the most content I've ever been. I feel like I got a second chance,” she previously said.
