Life is good for Erik Spoelstra.

The coach of the defending NBA champion Miami Heat has presided over his squad's 18-game winning streak, the longest in franchise history and in the league this season.

And, as if things couldn't get any more exciting for Spoelstra, the famously private coach recently stepped out with his girlfriend for the first time.

The Miami Herald reports that the 42-year-old coach is dating 24-year-old Nikki Sapp, a Miami native and a former Heat dancer.

Apparently Spoelstra has been dating Sapp for nearly two years, but the couple only recently made their relationship public. Sapp is now a director at the Guy Hepner art gallery in West Hollywood, Calif., and so she splits her time between Miami and Los Angeles.

Spoelstra and Sapp have attended a few charity events together -- the Miami Heat Family Foundation night of "Motown Revue" and a fundraiser for Lauren's Kids, a group that works on preventing the sexual abuse of children.
