Khloe plans Kim Kardashian's engagement party in four days

Kim Kardashian accepted a proposal, and 20.5 carat diamond ring, from NBA star Kris Humphries in May, and has hinted she'll wed this summer. And on Thursday sister Khloe threw a last-minute engagement party for the couple, when they realized it was the only opportunity to fit it into both families' busy schedules.

And she called in event planner Sharon Sachs, who planned Khloe's own wedding to Lakers star Lamar Odom in September 2009. "She did my wedding in nine days, so I was like, 'You can put together an engagement party in three days!' It was really fun!"

Almost 50 friends and family attended the bash in Los Angeles, including some friends who had yet to meet Humphries amid his rapid relationship development with Kim.

"Everybody had the best time and got along. It was so sweet see everyone hang out with each other."

When they wed, Kim has said she'll keep her last name professionally but will take his name with a hyphenate.

As for that 20.5 carat diamond ring? Humphries helped design it with jewelry designer Lorraine Schwartz. He spent days deciding which inscriptions to engrave on the platinum band, settling on Biblical phrases like, "Who can find a virtuous woman? For her price is far above rubies. The heart of her husband doth safely trust in her, so that he shall have no need of spoil."

Also included on the band was a simple "K [hearts] K."
