Naomi Campbell dating Uma ex?

Naomi Campbell has been seen out with Uma Thurman's ex-boyfriend.

The supermodel was spotted enjoying dinner with hotel mogul Andre Balazs at New York's Waverly Inn last week. The pair were joined briefly by top designer Donna Karan.

However, a source denies Naomi and Andre are an item, saying: "They aren't a couple. They're not really together."

Andre also took Naomi as his date to fellow model Kelly Killoren Bensimon's recent birthday party at hip Manhattan bar Pop Burger.

'Kill Bill' star Uma split from the handsome hotel owner in March just days after rumours surfaced the couple, who had been dating on-and-off for three years, were planning to marry this summer.

Uma, 36, and Andre, 50, were said to be planning to tie the knot on a secluded Caribbean island, with friends insisting "they can't keep it a secret much longer".

Uma's ex-husband, actor Ethan Hawke, was even said to have given his blessing and planned to attend the intimate ceremony.

In March 2006, Uma appeared at the Oscars without Andre, fuelling speculation the relationship had ended. Uma's publicist confirmed the split a few days later.
