Paris Hilton "cooks lasagna" for beau Benji Madden

Paris Hilton's wild ways seem to be a thing of the past now she's hooked-up with Good Charlotte rocker Benji Madden.

The hotel heiress, 27, has been busy cooking for her man -- and the former Simple Life's specialty dish is lasagna!

"The two stay home as much as they can, cooking dinners and just hanging out," a source close to the couple tells E! News. "She makes him her specialty dish, lasagna, and he loves it."

And instead of going out partying every night, the pair watch movies -- mainly comedies -- and cuddle up on the couch.

However, there's no double wedding in the pipeline with Nicole Richie and Joel.

"No way," says the insider. "Paris and Nicole aren't going to share their wedding day!"

That doesn't mean the pair don't intend to get married, though. "Paris has never been more in love," says the source. "She can really see herself settling down with Benji, because she totally trusts him. She's never had that with a man before. She knows he adores her and would never, ever hurt her."
