Sweet treats for the mommy-to-be! Jessica Simpson enjoyed lunch with her fiance Eric Johnson and BFF Cacee Cobb at the Cheesecake Factory in Los Angeles on Saturday, Feb. 16, and the threesome even took a few snacks home.

Simpson, 32, who stepped out for a Valentine's Day lunch dressed up in a festive pink blazer with Johnson, 33, at The Ivy earlier in the week, looked positively radiant in an all-black ensemble topped with a navy green jacket. She grinned at Cobb on the escalator as they made their way into the valet parking area.

NFL player Johnson similarly kept things casual in a grey hood and a San Francisco 49ers baseball cap. The daddy-to-be clutched a Cheesecake Factory takeaway bag in his left hand.

The happy couple, who announced their baby news via Twitter on Christmas Day just two months ago, is already preparing to make room for their expanding brood.

"She's already met with designers!" a source told Us Weekly of the singer's recent bid to buy Sharon Osbourne's $13 million 11,000-square-foot mansion in the Hidden Hills, Calif.

According to the source, Simpson plans to redo Osbourne's closet and turn it into a nursery for baby Maxwell's little brother or sister. Earlier this year, Simpson spoke with Jay Leno about her second pregnancy.

"We're doing it very backwards, I know ... I'll just keep my legs crossed, I guess, this time," the Fashion Star mentor joked, referring to her and Johnson's delayed nuptials. "Apparently it was a part of God's plan for my life."

"I was extremely shocked," she continued, about finding out about her second pregnancy. "Because I was going through a lot of hormonal changes, trying to get back to the old, vibrant Jessica. You know, it was kind of like a one-night stand. And it happened, all over again!"
