Billy Ray Cyrus put on a brave face while posing for photographers at the 44th Annual CMA Awards in Nashville Wednesday.

Hiding behind dark sunglasses, the outing marks the 49-year-old singer's first public appearance since filing for divorce from wife Tish on Oct. 26.

Sources recently told Us Weekly that Billy Ray decided to end his 17-year marriage after he learned of his wife's affair with Bret Michaels (both Tish's and Michaels' reps deny the report).

Despite the split, Billy Ray is set to reunite with his soon-to-be ex on Nov. 23 to celebrate daughter Miley's 18th birthday.

"[My family and I] need time to all be together," Miley recently told MTV News. "I'm not going to go crazy; [just] have a fun party and then maybe take a vacation with my family...because that would be really cool."
