Nas and Kelis may have split, but they remain linked for life through their now three-year-old son.  

Some pictures were taken at his birthday party in L.A. yesterday, July 22nd, and it looked as though Nas took him to the pool at one point.  Remember the days when you didn't know how to swim and you had to wear the inflatable arm floats to keep above water?  Those were the good ol' days.
