Actor Michael Vartan is confident his former Monster-In-Law co-star Jennifer Lopez will take to motherhood with ease - because she is already a very maternal person. The Alias star insists the mother-to-be will be a great parent - and has her Puerto Rican roots to credit for her loving nature. He tells New York gossip column PageSix, "I think she'll be a wonderful mom. "I think Latin women have the key - very emotional, very nurturing. You always hear about big Latin families and how close-knit they are." Lopez and her husband Marc Anthony are reportedly expecting twins in the next few weeks.
