Blaming their hectic schedules that kept them apart, reality star Khloe Kardashian has split with her boyfriend, Rashad McCants of the NBA's Minnesota Timberwolves, she says on her blog.
"He's in a different city every day for games," Kardashian, 24, writes. "Our time together was just so limited because of both of our schedules that we decided it is best not to be in a committed relationship. The last seven months have been great and we will definitely remain close friends."
She denies that the split with McCants, 24, was due to "either of us 'finding' someone else."
"It was based on a mutual discussion we had," she says, "and we realized that this is what makes sense for both of us."
