With Owen Wilson's usual bike partner, Kate Hudson, up north filming, the perfect substitute made his way to Miami this weekend: his BFF and often costar Vince Vaughn. Not sure Vince looks entirely comfortable on that bike, but he's a good sport for going along for the ride (get it!?). On Friday, Owen spent the evening out at the Shore Club with Richie Sambora and Dylan McDermott, but by Saturday it was all about Vince time, apparently partying at Casa Tua until about 5:30 a.m.. Owen's Marley and Me costar and Vince's ex, Jennifer Aniston, didn't join the boys but was busy making headlines of her own after being spotted dining with John Mayer. Interesting timing — I might be the only one, but I'd love to see a Jen and Vince reunion. Until that never happens, seeing these two boys together is fun enough.
