And as for those rumors about McConaughey and Armstrong being more than pals? "We tried it. Wasn't for us," the actor joked to Details magazine. 02 of 08 NICK & MATT John Sciulli/WireImage Sports fanatic Nick Lachey, 32, and Arizona Cardinals quarterback Matt Leinart, 23, have each other's backs. When the singer was named Cosmopolitan's Fun Fearless Male in February, Leinart was there. And besides sharing a taste for sports and nightlife, they make time for doing good: Together they paid a visit to the pediatric ward at Cedars-Sinai Hospital. 03 of 08 KANYE & JAMIE Kevin Mazur/WireImage They first bonded over their "Gold Digger" collaboration, and Jamie Foxx, 38, even credits his relationship with hip-hopper Kanye West, 29, as one of the reasons the ladies find him appealing: "I think that if you're confident, and you're poppin' with Kanye West and you had the No. 1 song in the country, that makes it a little sexy," he told PEOPLE last year. 04 of 08 BEN & MATT Ethan Miller/Getty Way before they were appointed Hollywood's golden boys for their Oscar-winning Good Will Hunting screenplay in 1998, Ben Affleck, 34, and Matt Damon, 36, had each other's back. "Ben's really loyal and really honest, really smart, really funny," says Damon. And we wouldn't be surprised if these childhood buddies from Cambridge, Mass., carry their friendship over to the next generation – to Affleck's 10-month-old daughter Violet and Damon's 4-month-old Isabella. 05 of 08 ANDY & JAMES Evan Agostini/Getty Though tennis stars Andy Roddick, 24, and James Blake, 26, are rivals on the court, it's totally friendly competition. Sure, they've got different personalities – Roddick is a fun-loving prankster, while Blake is a cerebral former Harvard student – but the guys keep each other grounded: When Blake appeared in a New York Times magazine fashion spread in 2003 before the U.S. Open, Roddick played a joke on him by covering the locker room with the photos. 06 of 08 GAVIN & BRAD ZXING / SNAP-PIX;(inset)Hal Horowitz/WireImage;dpa /Landov When Gavin Rossdale, 39, tied the knot with Gwen Stefani in L.A. in 2002, Brad Pitt, 42, was on the guest list. Four years later, they're family men delighting in their growing broods. This past July, the two clans even came together at Pitt's Santa Barbara home for a day of frolicking, including jet skiing and ATV-riding for the boys with Pitt's son Maddox by their side. 07 of 08 JONNY & JUDE Richard Young/REX FEATURES At Jonny Lee Miller's 1995 wedding to Angelina Jolie, Jude Law was his best man. And the 33-year-old actors even started the London-based Natural Nylon Theatre Company together (with Law's ex Sadie Frost and Ewan McGregor). Now both single men, the British blokes hit the party scene together from time to time, stepping out last month at L.A.'s Tropicana Bar. 08 of 08 OWEN & LUKE Dimitrios Kambouris/WireImage Even though Luke Wilson, 35, was something of an unwanted guest (hello, Dupree!) in brother Owen's home at one point, "The funny thing was after he left, I kind of missed him," says Owen, 37. And when it comes to their careers, the siblings are each other's biggest supporters. Says Owen, "We're not competitive about movies. If Luke's movie does great, that helps me, because I know I can always get Luke to do a movie with me."
