The key to Lauren Conrad’s heart?

Be a bad boy!

“Why don’t you like sweet guys?” Ryan Seacrest asked the Hills star on his show this morning.

“They’re not as fun!” Conrad, 22, admitted. Pal Lauren “Lo” Bosworth agreed, noting, “Sweet boys can be, like, filler.”

Conrad says she’s “easily bored” and dating is all “about the chase.”

“You want the game to be played,” Conrad, 22, says. “You don’t want to have a great time and him to call you right after!”

“It’s weak to text,” Conrad adds.

Seacrest, who said Conrad is “tragic in [the dating] department,” asked, “What’s with you and falling for these guys?”

Conrad replied, “I have no idea!”

The Hills returns with 10 bonus episodes beginning March 24.
