Megan Fox is going to be one foxy mama!

The pregnant This Is 40 actress, 26, showed off her growing baby bump in a tight, floral print dress while strolling through L.A. August 19 with her older sister, Kristi. Fox paired the dress with red velvet platforms and a stack of multicolored bracelets.

During an appearance on the Tonight Show With Jay Leno in February, Fox revealed that her older sibling once had the hots for Brian Austin Green, whom the actress wed in June 2010.

"I was on a sitcom called Hope and Faith on ABC with Kelly Ripa and Faith Ford," Fox recalled. "Brian was guest starring playing himself, but I was too young to have watched 90210, so I didn't know who he was. I just knew that he was gorgeous and I wanted to get to know him better."

"My older sister — I won't say her exact age, but she's in her 30s — she knew exactly who he was and she had been in love with him her whole life," Fox laughed. "He was like her Justin Timberlake, so it was very weird for her that I was dating him and now married to him."

Fox and Green, 39, are elated to start a family of their own. "They're thrilled about the baby. They're a great couple and very happy together," a source recently told Us Weekly. "Megan is going to be a great mom. She's already a great stepmom [to Kassius, 10, with Green's ex, actress Vanessa Marcil]."

A second insider says Fox "is doing well with her pregnancy and just trying to keep things low-key." Due this fall, the mom-to-be "could not be more happy," according to a Fox pal. "They've been together for so long and after taking care of Kassius with Brian, she knows she can handle it."
