Just in case anybody had forgotten that Kobe Bryant has never won an NBA title without Shaquille O'Neal, the big man sent out a reminder.

The Phoenix Suns center can be seen rapping that "Kobe couldn't do without me" in a video posted online at celebrity news and gossip site TMZ.com.

During the two-minute video, a grinning O'Neal lurches through an improvised rap in which he skewers the Lakers' star, with whom he won three straight NBA titles from 2000-2002 while with Los Angeles.

"I was freestyling. That's all. It was all done in fun. Nothing serious whatsoever," O'Neal told ESPN.com Monday. "That is what MC's do. They freestyle when called upon. I'm totally cool with Kobe. No issue at all."

O'Neal and Bryant last played together in 2004. The two had a falling out after Bryant was arrested in Colorado and charged with rape. Bryant reportedly told police that O'Neal would pay his women to keep quiet in similar situations. O'Neal was traded to Miami before the 2004-05 season, and won an NBA championship with the Heat in 2006.

Bryant and the Lakers didn't reach the finals again until earlier this month, when the Boston Celtics beat them 4-2.

"You know how I be," Shaq rapped. "Last week Kobe couldn't do without me."

O'Neal, who has recorded seven albums, also said he is "the difference between first and last place" and even took a jab at former New York Knicks center Patrick Ewing's lack of championship rings.
