Jordin Sparks is happy and healthy following her 50-pound weight loss.

The 24-year-old former "American Idol" winner spoke honestly about her weight in an interview Friday with the "Today" show.

Sparks says she was initially inspired to get healthy after she got "really sick" a couple of years ago.

"I was like, 'I should be in the prime of my life right now. I shouldn't be feeling this,'" she recalls. Her illness spurred her to make her health a priority, and she changed her diet and became more active.

"It does get a little crazy," the singer says of the pressure to be thin. "I think not succumbing to the pressure is harder than actually giving in to it."

Sparks divulges that she currently weighs between "155 to 161." She says she was "comfortable" with how she looked before her 50-pound weight loss, and asserts "it wasn't about being a zero or a certain size of anything like that."

"I know that there are some women who struggle to even look themselves in the mirror," she acknowledges. "And I hope that those women who are struggling can watch this and go, 'You know what? I'm OK with who I am. And I'm beautiful in my own way.'"
