Hollywood's Hottest Moms

This is a milestone year for Jennifer Lopez whose twins Max (at left) and Emme recently turned one and who will celebrate her five-year anniversary with husband Marc Anthony in June. The megastar takes every opportunity to be with the twins, including when she's getting her makeup done. "I try to put them on my lap and the makeup artist is like, 'Can you move her?' And I'm like, 'No! I have to have two babies on my lap!'"
