Since Lopez and 43-year-old Anthony split in July, the singer-actress has also been romantically linked to Bradley Cooper. A source told Us the Hangover star, 36, was "really trying to woo Jennifer in a big way" and the actor had been "after Jennifer, calling her, for ages." In addition to a super romantic candlelit Sept. 10 dinner at NYC's Per Se eatery, the charming Limitless actor stepped up his seduction game again with a secret flight to Boca Raton.

Lopez "liked the thrill and the fact that Bradley has been pursuing her," but a source says she "has really been trying to concentrate on her kids and work. But Bradley has been especially eager."

But Lopez doesn't pretend to be an expert relationships. She told Us last year prior to her split: "I'm not one to give advice on marriage. You have to communicate if you want it to keep on working."
