Dierks Bentley has been keeping his son Knox under wraps since he was born last fall, but the proud father finally shared a picture of his firstborn boy over the weekend.

Dierks and Knox were sitting around the house watching some football together when Bentley snapped the above pic, which is the first time he's shared a photo of Knox since he was born on Oct. 9.

“Watching football with my buddy knox," the singer tweeted. "He wants me to give a shout out to @LBTmusic for his new duds!”

The 38-year-old singer and his wife, Cassidy, also have two daughters, Evie and Jordan.

Bentley is slated to release his new album, 'Riser,' on Feb. 25. He will likely debut some of the new material when he headlines at the Tropical Nights Boots in the Sand getaway, which runs from Feb. 23-27 at the Riviera Maya in Mexico. Billy Currington, Brantley Gilbert and Jana Kramer will also headline separate nights of the luxury country music getaway.
