Jessica Simpson's BFF CaCee Cobb isn't due to give birth for several months, but it sounds like she already has her hands full taking care of husband Donald Faison. On Wednesday, Feb. 20, the pregnant 31-year-old joked that the Scrubs actor, 38, wasn't exactly living up to his role as man of the house while both were feeling under the weather.

"I love how I'm sick and growing a human while Donald Faison is sick and growing a vagina," the mom-to-be quipped on Twitter about her spouse of two months. (The couple wed at pal Zach Braff's home in California on Dec. 15, 2012, a little over a year after they got engaged.)

Cobb and Faison announced that they were expecting their first child together on Jan. 31, with a photo of a tiny T-shirt featuring a baby-sized Star Wars stormtrooper on Facebook. "Looks like Donald Faison and I are going to have a little stormtrooper of our own!" the soon-to-be first-time mom captioned the adorable snapshot.

Faison -- who has four kids from previous relationships, including three with ex-wife Lisa Askey -- couldn't be happier about his fifth little bundle of joy, even if (as Cobb's tweet suggests) he's being a bit of a baby himself at the moment. "I'm just excited for CaCee," he told Us Weekly earlier this month. "She's probably the most loving person I've ever met in my life."

He added: "And so for her to have a baby that she can love and you know, raise, and that we can raise together, and she can influence and teach and stuff like that, it just, I know that it'll be a really good human being when it's older."
