Who knew Paris Hilton cooked? Let alone ate big pasta dinners.

But apparently, she's doing a lot of both since hooking up with steady beau Benji Madden.

"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."

(Just hope he doesn't hear that she made the same meal for her ex Stavros.)

The lovebirds also keep it simple in every other respect. They watch movies (comedies mostly, we're told). And cuddle. He's even teaching her his favorite sport, skateboarding.

We haven't seen Paris this domesticated since...well, never. Could they even be talking about a double wedding with Nicole and Joel?

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

Besides, she's already warned him that one day, she'll want a huge wedding, with a formfitting designer gown. And an extended honeymoon, somewhere sunny and exotic.

He's hinted that when the time comes, she'll get a ring with so much bling, the glare will be blinding.

"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."
