CaCee, who was working as Jessica's PA during the Newlyweds years, is expecting a little girl with her Clueless star husband Donald Faison.
Donald played Dionne's boyfriend Murray in the hit 90s movie and he and CaCee are already parents to one-year-old son Rocco, who they welcomed in August 2013.
Yesterday, Jessica spent the day with CaCee and shared a gorgeous photo of her pregnant pal with fans on Instagram. CaCee is posing alongside another mum-to-be and Jessica commented: "Bumpin' Babies!"
CaCee and Donald, who also starred in TV comedy Scrubs, married in an intimate ceremony in Los Angeles in December 2012.
US singer Jessica was, of course, her bridesmaid and was pictured at the couple's wedding in a gorgeous black gown.
