Jessica Simpson's slow romance

Jessica Simpson is taking things slowly with her new boyfriend Billy Corgan.

The singer-and-actress doesn't want to rush into anything too serious with the Smashing Pumpkins frontman following her split from American football star Tony Romo.

A source said: "They are getting to know each other. He's a nice guy."

On September 11, Jessica tweeted: "My friend, Billy Corgan, has a pure and enlightened outlook on faith."

Jessica - who, at 29, is 13 years younger than Billy - was pictured leaving New York's Ritz Carlton Hotel with Billy last week.

The pair were first romantically linked in November when they both attended a party in Los Angeles.

A source said: "She has completely fallen for Billy and his easygoing, smart attitude. She says she wants to take things a lot further.

"She had secretly been crushing on him for months and felt there was a connection at the party.

"As the night went on things got more intense and they talked with their faces just inches apart."
