Jessica Simpson is bouncing back beautifully after baby! The 33-year-old mom of two, who gave birth to son Ace just two-and-a-half months ago, looked positively radiant at fiance Eric Johnson's 34th birthday party in Santa Monica, Calif., this past weekend.
Flashing a big smile for the cameras, Simpson showed off her fit post-baby body in a flirty black minidress, which she paired with a black-and-white printed jacket. Her long blonde hair was styled sleek and straight, and she rocked dramatic, smoky eyes and a pale peach lip. Big earrings and sexy black pumps completed the look.
The fashion mogul, also mom to daughter Maxwell, 16 months, pulled out all the stops for her husband-to-be's big day. Pictures from the weekend show Simpson and the former NFL player celebrating with BFF CaCee Cobb, sister Ashlee Simpson, and actor Dave Annable, who also turned 34 on Sunday, Sept. 15. The festivities included bowling and dinner at Benihana.
"Birthday weekend!!!" the Weight Watchers spokeswoman captioned one photo of herself and her fiance on Sept. 14. "I love you with everything and more and more and more..."
Alongside another photo of herself and Annable's wife Odette Annable, she wrote: "#HappyBirthdayWeekendHubbies."
Simpson recently opened up to Us Weekly about her relationship with Johnson, whom she started dating in 2010. "Eric is beyond any father that has ever existed," she gushed. "He will do it all without complaint. I can honestly say that I have not had to change many diapers! At the same time, he makes me feel like I'm an incredible mom and still a great lover and woman. And I still get my back rubs!"
The couple had to postpone their wedding in September 2011 when Simpson got pregnant for the first time, but they hope to tie the knot in the not-too-distant future. "We have started talking about it again," she shared with Us. "It's good because we ended up changing our minds about the original plan. We now have a where and when."
She added: "Everyone has just been so anxious for us to get married -- including us. And everyone has watched our love develop throughout becoming parents. When we actually do get married, it will be that much more intimate and beautiful. I don't think there will be a dry eye in the place!"
