The 46-year-old actress turned up at the EOS ORCHESTRA gala at the RITZ CARLTON in New York with interior designer TONY INGRO, following her split with author MARK LEVINSON.
And her new beau was ready to show he's got the cash to keep Cattrall in the manner to which her high-flying character Samantha Jones has become accustomed. He shelled out $10,000 (GBP6,600) for the right to lead the famous orchestra for one night.
An onlooker tells gossip website PAGESIX.COM, "They spent the night cuddling and kissing."
However, a spokesperson for Cattrall insists, "They are best friends. They always act like that."
