COVER STORY: Ali Fedotowsky — "How I Lost 10 Pounds Fast!"

The Bachelorette has been a whirlwind for its star Ali Fedotowsky. The 25-year-old blonde has endured the roller coaster of emotion that comes with reality romance — happiness with her attraction to Roberto Martinez and Chris Lambton, then heartbreak as Frank Neuschaefer recently revealed he has a girlfriend. But Ali’s feelings weren’t the only thing that went up and down on the show — so did her weight.

“I was always hungry!” Ali tells OK! of packing on 10 pounds while filming. “I didn’t think much of it, but everyone noticed.”

Today, she’s lost the weight and is happy. In an exclusive OK! photo shoot only in this week's issue, Ali debuts her amazing new body and how she did it. She shares what’s up with The Bachelorette and reveals what’s next for her in life.
