H'wood Party Girl

Kim Kardashian and Reggie Bush owe Matt Leinart big-time. The fellow footballer is actually the one who introduced the lovebirds to each other at the ESPY Awards.

So the least this couple can do is show up to support their friend when he throws a charitable fete. Case in point, they hit Matt's 2nd Annual Celebrity Bowling Benefit at Lucky Strikes Lanes in Hollywood last night with little sis Khloe in tow.

As for why the younger Kardashian joined them...

We're guessing she wanted to work on her bowling skills before her time in big house. She could have saved herself the trouble. Khloe checked herself into jail this morning but was released just a few hours later.

And while Khloe couldn't talk to any press Thursday night, big sis Kim (who's had her fair share of scandals to deal with) told E! News that her sister would be OK.

"She's ready to take responsibility and deal with it," Kim dished. "We're ready to move on."

Mission accomplished.
