J.Lo and Ben's relationship has been rocky since they called off their wedding last September (03) blaming "excessive media intrusion".
However pals have told British tabloids the pair regularly disagreed settling down and starting a family, which has caused the final split on Tuesday (20JAN04).
The singer and actress' intentions were to settle down and have children as soon as possible, just as she hoped for with her ex-husband Cris Judd, however her fiance Ben did not share her enthusiasm.
A pal says, "She wanted to spend the rest of her life with him and start a family, but he couldn't give up his bachelor lifestyle."
The last straw for J.Lo was the photos of her lover partying wildly with actor pal Matt Damon and a large group of sexy girls in a German nightclub earlier this month (JAN04).23/01/2004 14:10
