"It was insane how quickly we threw it together," Khloe, 27, wrote in a Thursday blog entry (accompanied by a whopping 81 photos). "We decided on a Monday that we were going to have it and then it took place that Thursday! We are nuts but we all have such busy schedules that this was the only time we could all do it."
"Even with just three days to pull it together, the party turned out fab," she added. "Kimmie and Kris loved it, which made me so happy!"
"She did my wedding in nine days, so I was like, 'You can put together an engagement party in three days!'" Khloe told Us Weekly in June. "It was really fun."
Nearly 50 close friends and family members attended the celebration, including several who had yet to meet the New Jersey Nets player, 26.
"Everybody had the best time and got along," Khloe told Us. "It was so sweet see everyone hang out with each other."
