An intimate dinner date between Jennifer Lopez and Bradley Cooper over the weekend has sparked off rumors about whether the two are dating.

The stunning 42-year-old singer and the handsome 36-year-old Hangover star met in New York City's Per Se, a swanky upper westside restaurant, and indulged in a nine course meal. The couple enjoyed a prix fixe meal that costs $295 a person. They were engrossed in conversation with each other.

According to a report in HollywoodLife.com, a witness at the restaurant told the Web site that the couple was indeed there and VERY flirty.

A host at the restaurant told Us Weekly that people came to the restaurant for privacy and that JLO and Cooper shared a meal just the two of them on Saturday.

However, E! cited a source close to Lopez who said the two were just talking about a possible movie project over dinner. Bill Zwecker of the Chicago Sun Times also wrote that the two met to see if they truly had chemistry that would work in a proposed romantic comedy film project. People carried a report with a source saying that the duo is in discussions regarding a project.

Lopez recently split from Marc Anthony, her husband of seven years. Cooper's two-year romance with Renee Zellweger also ended in March.
