During a guest-hosting gig on Anderson Live, Rosie O'Donnell opens up about life after her heart attack and says she is successfully losing weight in her transition to a healthier lifestyle.

While Anderson Cooper is on location reporting on the latest developments in the Middle East, Rosie teamed up with Real Housewives of Atlanta star NeNe Leakes to hold down the fort on his daytime talk show.

"Feeling a lot better, thank you," Rosie said in response to a viewer's question about her health status after suffering a heart attack in August. "I got my number yesterday, I am way up there. I don't mean weight, I mean like good like blood pressure and I've lost like twelve pounds. We are going for a pound a week."

When co-host NeNe tells Rosie she's looking good, she responds by addressing her health scare. "Thanks, you know I had a heart attack. I keep telling everyone I had a heart attack and my kids are like, 'Will you shut up already?' And I am like, 'No, I had a heart attack.'"

NeNe then reponds: "Well you know what, you don't look like a person who had a heart attack. Your hair looks full, I love how you're looking."
