Meg Ryan is house hunting in Chelsea after putting her Bel Air mansion on the market. Ryan was spotted touring a $10.95 million townhouse at 233 W. 20th St. The seven-floor home features a rooftop terrace, a garden-level solarium and patio, two kitchens and a wet bar. Listing agent Tom Postilio of Core had no comment. Ryan has listed her six-bedroom Bel Air estate for $11.4 million, and has been looking at downtown pads with rocker boyfriend John Mellencamp.
