Khloe Kardashian has thrown her sister Kim a last-minute engagement party.

The 30-year-old socialite got engaged to basketball star Kris Humphries last month and younger sibling Khloe, 27, wanted to mark the occasion with an exclusive bash for close friends and family, but had just three days to plan it.

Speaking about the party - which took place last Thursday (16.06.11) - Khloe said: "We obviously move really fast in my family. We're so crazy busy, and Kris was going back to Minnesota to be with his family. We were trying to find a day where the two fiancees could be there with all of us. On Monday (13.06.11), we realised that Thursday was open, so I was like, 'Am I really going to throw a party on Thursday?' "

Khloe - who married basketball star Lamar Odom in 2009 - enlisted the help of her wedding planner to help organise the party.

The reality TV star said: "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."

Khloe says the engagement party was a great way for Kim and Kris to meet all of each other's friends and family.

She told Us Weekly magazine: "Everybody had the best time and got along. It was so sweet see everyone hang out with each other."
