Now that Jessica Simpson has delivered Maxwell Drew (who weighed in at 9 lbs, 13 oz when she was born), she is focusing on getting her body back in shape. She told People:

“I think anybody who’s gone through a pregnancy, after they have the baby, it’s like, ‘I need to do something about this.’ For me, I really want to do something that is a lifestyle, because in the past, I’ve been known to yo-yo diet.”

And it looks like those Weight Watchers rumors were true (at least that she’s doing the program), based on Jessica’s tweet from last night:

So excited to be a part of the @WeightWatchers family!

Jessica said she’d been planning to do Weight Watchers before she found out she was pregnant, but once she got the news, she stopped the program.

“I was like, ‘I’m going to enjoy my pregnancy,’ and I did. I ate very healthy, but I did indulge some of my cravings – and that’s okay because I know I can work it off now.”

Jessica said that she doesn’t have a goal weight: she just wants to “feel normal and fixate on inches.” She plans on achieving small goals: smart girl. But goodness, Jessica, give yourself some time! She doesn’t have much choice: Jessica also admitted to People that she hasn’t been cleared by her doctor to exercise yet.
