According to a report in, 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.
