Gwen Stefani has learned a basic truth about being a parent: You always feel guilty. Especially if you are a woman juggling work and home.

"Getting to the studio and not being able to make it happen, but missing out on being at home, missing out on putting the kids down. What's more important? I felt so guilty," the No Doubt singer tells Vogue of raising her two sons with hub Gavin Rossdale, Kingston, 6, and Zuma, 4. Gwen, 43, says she kept thinking, "I am letting everyone down. . . . I'm letting down my kids; I'm letting down myself." Things were especially tough during the year Gavin toured with his reunited band, Bush. "Once you have a family, it's just so obvious how everyone needs each other," she says. "So it's really nice to have him back." Adds Gwen, "It's super fun being a mom, but it's not what you think it's going to be."

Romeo, Romeo, thou art Burberry

Lil Wayne, very big wallet    

Lil Wayne, 30, just dropped $7.72 mil in one go. Alas, he wasn't buying a used Lear Jet or 38,600 bottles of Louis Roederer Cristal Champagne Brut 2004.
