Serena Williams (L) and Common

*Serena Williams and Common were spotted at a small private event Friday night in her hometown in Compton, sparking rumors that the former couple are rekindling their romance.

According to TMZ, an eyewitness says the tennis star and the rapper/actor were in a back room chatting before she spoke to the audience at the grand opening of the Yetunde Price Resource Center — for people affected by violence.

Via TMZ:

We’re told the exes were careful to avoid taking pics together, but individually each got a photo with Compton’s mayor, Aja Brown. They left in separate cars after the event.

Venus Williams was also there — the sisters launched the center because their older sister was shot and killed.

Serena split with Common in 2010 after at least a year-long relationship. A source close to them tells us they’re still just friends. The witness insists they seemed like more than buddies.
