Fresh off of a lengthy break from the spotlight, Ashlee Simpson was all smiles as she stepped out for a Reebok event in Los Angeles. Looking in fine form, the former "Melrose Place" actress was busy singing her praises for the Easy Tone sneakers - which she credits for snapping back into shape after her pregnancy. Talking about the transformation, Ashlee told E! Online, "I gained 50 pounds, which was awesome! I ate cake and cupcakes. I had a blast!"

Once ready to lose the extra pounds, Miss Simpson said of the process, "When I wanted to get back into shape, I worked out and these shoes are amazing because you can really feel them in your booty. But I also worked out and ate healthy."Also explaining her decision to lighten her workload, Ashlee told, "Being a mom is my first priority and it's amazing because you grow up and watch your child grow up. It's the best thing in the whole entire world."
