Rebecca reveals how she lost 60 pounds in four months – and it ain’t by eating Romijn lettuce!

The Ugly Betty star and mother of new born twins was 35 pounds lighter after giving birth to twin Charlie and Dolly – and then she dropped even more!

The former model’s secret?  Breastfeeding!

"Breastfeeding is the very best diet I’ve been on," Rebecca confessed.

"It’s amazing.  It’s like you have to eat 5,000 extra calories a day or you can’t produce enough food for them. So, that’s been fun as well."

"I’m not pretending to be back to the shape I was in beforehand. I still have a way to go."

Either way we’re sure hubby Jerry O’Connell is a happy man.
