Molly Sims' baby bump is so festive!

The pregnant actress took to Instagram on Wednesday, Dec. 21 to share a cute photo of herself showing off her belly while decorating the Christmas tree. Molly has been flaunting her bump in a plethora of stunning outfits over the past few months as well!

"Can't work out but I can decorate a tree like it's nobody's business!!!??" the 43-year-old model captioned the cute pic.

Molly and her handsome husband, Scott Stuber — who married in September 2011 — announced they are expecting Baby No. 3 back in August 2016. "We never expected it would happen, we didn't even know. This is such a true surprise, I think that's why I'm so emotional. He or she will be here before we know it," she said at the time.

Weeks after, she posted an adorable gender reveal video to share that she's having a boy! Her little guy will join big brother Brooks, 4, and sister Scarlett, 21 months. "Brooks is really excited about having a baby boy. He's already named it Jack and the Bean Stalk-Batman, that's his full name. And it's been really sweet to see him so involved and kiss my belly," Molly said during the reveal.

However, the 43-year-old has opened up in the past about how being pregnant for a third time at her age isn't easy. “Being 43… we wanted to tell everyone, but we were super nervous about, you know, the testing… so it’s just been really, really stressful, but everything so far is on track,” she admitted back in September.
