Rosie O'Donnell is down 50 lbs.

The former co-host of "The View" shows off her impressive weight loss.

O'Donnell recently admitted to undergoing gastric sleeve surgery in an attempt to shed about 80 lbs. She's well on her way according to the before and after comparison she shared with her fans. The star captioned her big reveal with "almost 50 lbs. off -- I can see it now."

With her toned neck and trim face, Rosie's makeover is impressive. It's helping the star stay healthy.

A year before her surgery, Rosie was hit with a heart attack when doctors discovered one of her arteries was 100 percent blocked. Luckily she made it through and is now an advocate for heart disease prevention in women.
