NBA Superstar Chris Bosh renunited with his GF and proposes to her...how sweet!

You'll never guess which ON-AGAIN-OFF-AGAIN couple are getting married . . . NBA superstar CHRIS BOSH and Adrienne

You'll recall that MediaTakeOut.com told you last month that the couple DECIDED TO SEPARATE . .. with Adrienne returning to her home in CANADA.

Well the two managed to work out their troubles. And not only are they getting bak together, they're getting married.

Here's what our pals over at the NY Post are saying:

"Chris proposed to Adrienne outside their new home in Miami at sunset. They then went out and celebrated with friends at Liv Nightclub, where Adrienne was seen showing off a huge diamond ring.

They are both really happy."
