The 25-year-old television star famously struggled with her weight as a teenager, and has become more and more slender recently, now boasting an enviable figure.
Kelly was thrilled when the health and fitness magazine Shape asked her to be a cover star, joining the ranks of beautiful models and athletic celebrities who regularly feature, and she says the public will be shocked when they see her image on magazine stands.
The pretty star also said she got very emotional during her accompanying interview, even shedding a tear.
“Just got done shooting the cover of shape! I cried in my interview I just can't believe today happened it you’re not going to believe ur eyes! (sic),” wrote Kelly on her Twitter account.
Kelly says most of her tears that day were tears of happiness though, as she was so happy to finally be wearing skimpy swimwear. Kelly admits she never thought the day would come where she would feel comfortable revealing so much flesh.
“I just got done trying all the bikinis on I have never worn one in my life! I had little tears of joy moment in the bathroom!” she added.
The star says she would love to have posted the gorgeous new pictures on her Twitter page, but she isn’t allowed to reveal them before the magazine hits the shelves. She teased fans by telling them they will just have to be patient.
“I wish I could tweet a pic but I'm not allowed you will just have to wait and see!(sic)” wrote Kelly.
