"Enough said," the 35-year-old star captioned a pic of herself wearing the silly suit.

The girls jetted off to Mexico to celebrate Chavez's 40th birthday. "Forty is the new 20!" Simpson said of her friend, adding the hashtag #HotMama. "I love this woman."

No doubt Simpson is looking better than ever, and she recently revealed to InStyle her exercise regimen. "I work out five days a week: three days with a trainer, doing a mix of strength training and cardio, and then I do cardio on my own the other two days," she said. "Somehow I make it work, but I've slowed down since my wedding."

When ET spoke to Simpson, she admitted that she doesn't follow a strict diet. "I think being a mom is enough of a diet," she quipped. "You have to run around chasing your kids, but I do eat a lot of their corn dogs, so I have to get on the treadmill a lot to watch my TV shows."
