Can't wait for eight more episodes of The Hills to see what "really" happens when Lauren Conrad and Whitney Port went to Paris to "work"? Well, we've got the deets on their Parisian romances…and the backstory behind them.

MTV producers wanted LC and Whitney to hookup (with guys, not with each other) while in Paris, and they didn't leave anything up to chance, a la the Gavin Beasley incident. So before they jetsetted to France, the producers were "frantically calling publicists to see if anyone knew any guys to set the girls up with in Paris," an insider tells Page Six. The lucky men were from the band Rock & Roll ("the King Cobras of New Wave Rock") who will appear in this spring's Roberto Cavalli campaign. "Lauren was filmed riding off with the guitar player, Matthias, on the back of his bike," our source said. "They hooked up." Man, we wish we had someone constantly hooking us up like that!

P.S. -- Sources for Page Six also confirm that Heidi Montag and Spencer Pratt "are completely together" despite breaking up on the season finale and Heidi showing up at the finale party sans Spencer and engagement ring.
