An Internet betting site has started taking odds on the name of pop couple Jennifer Lopez and Marc Anthony's first child together - and gamblers like MARCO. The experts at Bodog.com are offering 4:1 odds on Marco and 5:1 odds on Maria. Other names in the mix are Antonio, Rosario, Felipe and Selena, the slain Tejano singer Lopez portrayed in a 1997 film. The odds makers are even offering Ben as a 15:1 longshot, feeling Lopez might honour her ex-fiance Ben Affleck if the child is a boy. Online gamers can also bet on the month of the baby's birth - with April (08) a clear favourite at 2:1 - and the child's birthsign. After weeks of speculation, Lopez confirmed she was pregnant with her first child during a concert in Miami, Florida last week (07Nov07).
