The Latina actress, 30, struck up a friendship with Oscar-winner Foxx when he invited her to star in his latest music video.
Longoria and Foxx attended Mary J Blige's surprise birthday party in Los Angeles last Wednesday (11JAN06), before speeding off together in the RAY star's silver two-seat Lamborghini.
After attending the Golden Globes alone on Monday night (16JAN06), the actors walked the red carpet of the InStyle and Warner Bros post-awards bash together and were photographed hugging at the party, before leaving together.
Despite her frequent meetings with Foxx, Longoria insists she is still with the San Antonio Spurs player, who she began dating a year ago (JAN05).
She says, "I did Jamie's music video for him, so we're friends. And he has Tony's blessing."
