Luke Bryan got his second fishing partner with the birth of son Tatum Christopher, who arrived a week earlier than planned at 9:48 a.m. Wednesday morning. He weighed in at 6 lbs., 8 oz.
“All I ever hoped for was one boy and to have two, it’s going to be fun. I’ve already got new fishing spots picked out for us,” Bryan, 34, tells PEOPLE exclusively.
The singer called from his cell phone while at a local Sonic where he was picking up a lemon berry slush for wife Caroline, 30.
“I had planned to buy her a little present today but then the baby came early, so the slushie will have to do it for now,” he explains with a laugh.
