It's not unusual for celebrities to go to great lengths to keep their love lives private. And it looks like that's exactly what NBA superstar Lebron James and R&B singer Kelly Rowland are doing. MediaTakeOut.com has learned that the two may be carrying on a secret relationship.

In an exclusive interview, we spoke with an NBA insider who claims that Kelly and the NBA All-Star have been seeing each other for months. Our source tells, "I first figured that something was up when I would [see] Kelly at the games ... But when I started seeing her in the locker room [area] and at practices, I knew something was jumping off."

And the insider claims Lebron's manager Maverick Carter is helping the two keep their relationship a secret. According to the insider, "Kelly is telling people that she's dating Lebron's manager - but that's just to throw people off ... she has to have some excuse for always being around."

But if the two are dating - why the need for all the trickery? One possibility is that Lebron wants to keep the relationship from his pregnant baby's mother Savannah. The couple, who were high school sweethearts, already have a son together and publicly talk about getting married.

But our tipster believes that there's another reason. According to the tipster, Kelly doesn't want her good friend Angie Beyince to find out about her NBA fling. The tipster explains, "Angie and LeBron used to date and she's not over it yet." Angie, who is Beyonce's cousin, reportedly dated Lebron last year. At the time Lebron was still in a relationship with Savannah.
