Kevin Durant has been hanging out with James Harden, but the free agent-to-be apparently isn't interested in playing with him again.

Durant has ruled out the Houston Rockets despite their interest in him, ESPN's Marc Stein reports.

Durant and Harden teamed up on the Thunder for three seasons before Harden was traded to Houston, where he has become the franchise player he couldn't be in Oklahoma City.

The Thunder reportedly are considered frontrunners to re-sign Durant on a two-year max contract that he can opt out of next year. But the Golden State Warriors and San Antonio Spurs are expected to be among several teams making a strong push for the 27-year-old superstar -- and apparently the Celtics, too.
