Laguna Beach babe Kristin Cavallari and

Entourage's Kevin Connolly (aka Nicky Hilton's ex) made it clear they were a couple at the House of Hennessy at Super Bowl XLII party, presented by 944 Magazine and Tao Nightclub Sunday evening at a private mansion in Phoenix. Cavallari and Connolly imbibed and danced, and a partygoer says Cavallari (apparently taking her cue from Paris Hilton's alleged Elisha Cuthbert escapade) asked other girls to "make out with her." Cavallari, obviously not on the Zone diet, throughout the evening indulged in hamburgers and Hennessy cocktails (as did Connolly, while gabbing with Ryan Seacrest), and later left with the Entourage star. New uncle Benji Madden talked to Cisco Adler (who was shooting a new reality show at the party) about his brother Joel's new baby, Harlow, and proudly discussed the new parents' sheer joy. Richie's ex, DJ AM, meanwhile spun tunes all night long. Madden also hung with ex-Atlanta Falcon player Jamal Anderson, described as "a big flirt with the bartenders." Reality star Brody Jenner showed up with 12 friends, including Frankie Delgado. Later, when Jenner wanted to leave, he snapped his fingers and said to his crew, "I'm out. And they promptly ran after him." What power the Olympian offspring wields! More celebs (and those who aspire to be) on hand for the soiree included Ian Ziering, Stacey Kiebler, Dylan Walsh, Khloe and Kourtney Kardashian, 50 Cent and Spencer Pratt. - N.F. Mendoza
