Odom, who was allegedly due to go to the New Orleans Hornets, was traded from the Los Angeles Lakers to the Dallas Mavericks, reports the Los Angeles Times.
Kardashian told one of her followers on Twitter: "We are all sad but positive energy gets you farther then negative.
"I am sure I will love it but I am a tad thrown off," she also wrote. However, she added: "I have no doubt about it! I am excited. :) I know this is for a reason."
The couple, who wed in 2009, celebrated their two-year anniversary in September.
In celebration of their wedding anniversary, Kardashian wrote on her website: "730 days, and I still feel like a newlywed, I still blush when my hubby says my name, and I still get giddy when he's about to walk in the door. I truly am the luckiest girl in the world and I count my blessings every single day."
