Khloe Kardashian has her own cash to burn, thank you very much.

The reality star was peeved on Tuesday after blogs speculated she didn't pay for her lavish gift -- a $400,000 Rolls Royce -- to hubby Lamar Odom.

"People r so pathetic," Kardashian, 25, Tweeted. "Y would I give some1 a gift w/ their money? That's lame. I actually make my own money. Shocking I know. Stop hating!"

Her mom Kris Jenner told E! News that Khloe had congratulated Odom's Lakers championship with "a brand new 2010 Rolls Royce...drop top coupe, white on white."

On Monday, Khloe -- plus Jenner, sister Kendall and Odom's kids Destiny and LJ -- road the float with Odom and his team in the Lakers parade.

"It was one of the most unbelievable experiences of my life," she wrote on her blog.
