The former couple stayed far away from each other and were not seen conversing during the game. Gwen stayed on the side with their son while Gavin walked around in the background. It was the first time Gwen and Gavin had been seen publicly since the singer got married to her new husband Blake Shelton in Oklahoma.
As RadarOnline.com previously reported, Gavin reportedly has been having a hard time with Blake becoming stepdad to his kids with Gwen.
A source told OK! Gavin has been "ticked off at Blake in the past for seemingly overstepping his bounds, and is ready to make it clear he has final authority with the boys.”
Gwen met Blake on the set of The Voice in 2015, the same year her divorce from Gavin was finalized. The pop star and her ex were together for 13 years and share 3 kids.
Per their settlement, they share joint custody as they both own mansions in California. Gavin played nice in the divorce and agreed to take less than 50% despite no prenuptial agreement being in place.
