Jessica Simpson is ready to give Sharon Osbourne's closet a makeover! The pregnant-again star -- who is in escrow to buy The Talk co-host's 11,000-square-foot mansion with fiance Eric Johnson -- has told pals Osbourne's huge walk-in closet will become Baby No. 2's nursery, a source reveals in the Feb. 18 issue of Us Weekly. The Hidden Hills, California, home was listed at $13 million.

"She's already met with designers!" a source tells Us of the Fashion Star mentor, already mom to daughter Maxwell, 9 months. Simpson, 32, and Johnson, 33, got engaged in November 2010 and have pushed back their wedding twice due to the singer's pregnancies.
