I was just flipping through the current issue of US Weekly(don’t judge-I was in a waiting room and there was nothing else to read,lol) and saw an article about the April 16 wedding of Paramount CEO Brad Grey,which Gwen and Gavin attended along with other celebs like Tom Cruise and Katie Holmes,Jennifer Lopez and Brad Pitt.The article said that Gwen and Gavin performed a song together at the reception! It didn’t mention what song it was (maybe another rendition of ”The Sweetest Thing”? đŸ˜‰ ) but it’s cute to think they duetted!
