Brittney Griner's just days away from returning to the WNBA court -- and anticipation is at an all-time high for Mercury fans -- but the pot is about to get a little sweeter ... 3x Grammy winner Wyclef Jean will be performing a special halftime show in honor of BG's homecoming!
TMZ Sports has learned the Phoenix Mercury have teamed up with The Sum, a new music platform, to bring in Jean to perform during their May 21st game against the Chicago Sky at the Footprint Center to celebrate Griner's return on what will be her first home game since the Russia ordeal.
