"She'll be a wonderful mom" to newborn Maddie Briann, said Sims, 26, at the opening of Beverly Hills boutique Shizue on Thursday. "I'm really excited for her."
As for the family, Sims said, "You know, I haven't talked to 'em, but I know she'll have so much fun, and the baby will bring her so much happiness."
Sims had similar praise for aunt Britney Spears, saying, "She'll be so much fun!" and predicts Brit will buy baby Maddie "lots of pink, fun, girly stuff."
While Sims says she plans to visit Jamie Lynn "very soon," she's also busy working on a debut album: "I'm going to spend August in Nashville writing and recording."
