Ashley Olsen has a new ''very rich, ancient'' boyfriend.

The 30-year-old fashion designer - who was previously romantically linked with George Condo, 59, Bennett Miller, 49,

and David Schulte, 47 - reportedly attended an exercise class at Flywheel Flatiron in New York with Richard Sachs and stunned other attendees with their closeness.

A source told the New York Post Newspaper's Page Six column: ''They sat in the front row of the spin class and rode on bikes next to each other. They were ­affectionate after the class, despite being sweaty. She covered up in a big jacket and huge black sunglasses.

''They were canoodling and cuddly when they left holding hands. He looked like he could be twice her age. There's no way that's his natural hair colour.''

Ashley and Richard were also seen a few days before their exercise class taking a stroll around the Hamptons together.

The former child star's new man is described as a ''bigwig in the art space,'' who is divorced and divides his time between New York, St. Barts and Malibu.

A source said: ''He has a lot of money from working in ­finance. He's a great guy who owns a lot of art. I believe he's in his late 50s. He's always at the art parties.''

Another insider added: ''[He is] really good guy. His passion at this point in his life is supporting young artists. He is very private and a little eccentric.''

Despite Ashley supposedly spotted on a date with George in June, with onlookers stating their arrangement looked ''romantic'', a representative for the painter was adamant at the time that they had simply met up for a ''business meeting'' and were not dating.
