Khloe Kardashian sure knows how to say congratulations. Proving that she too is a baller, she rewarded hubby Lamar Odom with a brand-new car for winning the NBA championship. But we're not talking about just any car -- the reality star sprung for a 2010 Rolls Royce, which only set Khloe back about $400,000. That is apparently a small price to pay to say "good job." Khloe's mom Kris apparently approved of the lavish gift. She tells E!, "It's a brand new 2010 Rolls Royce ...drop-top coupe, white on white. It was a Lakers championship present. Fabulous!" The Lakers player, who tied the knot with Khloe after just weeks of knowing each other, appreciated the gesture, as he was seen cruising around in his new ride on Father's Day. Khloe can't say enough about her hubby's victory. She posted on her Web site, "What a year this has been for Lamar!!!!! Cheering on my hubby from the stands and watching the Lakers win the NBA championship last night was one of the proudest moments of my life!!!"
