"She's definitely ready to pop," Simpson's fellow Fashion Star mentor, designer John Varvatos, told reporters at his 9th Annual Stuart House Benefit in L.A. Sunday. "I think she's going to be amazing. She's the sweetest, kind of down to Earth, All-American girl."
According to Varvatos, Simpson, 31, "is a family girl. She's never anywhere without her mom, and her dad's with her all the time. For her, it's really all about family," he said.
"I think what's so amazing about her becoming a mom is that I think it's kind of finishing off that other missing piece in her family," Varvatos added.
Simpson and Johnson are excited to become first-time parents this spring, and they've already come up with a name. "We're embroidering it on things," Simpson recently told ELLE. "It's nothing shocking and nothing you'll have to add to the dictionary. When people hear it, they'll know why."
