“Enjoying my first Father’s Day with my family! #blessed,” he wrote along with the snapshot on Sunday.
In the photo, Reggie, 28, wearing a suit and tie, cradles his 6-week-old daughter, Briseis, in his arms. They both don matching grins for the camera.
“When you have a child, everything you do is about them,” the NFL player told In Touch after he and his girlfriend, Lilit Avagyan welcomed Briseis on May 6. “You’re thinking about your child first. Everything.”
Reggie also told the mag that he had no plans to reach out to Kim, 32, when she had her baby.
“We’ve been focused on the future,” he shared, who dated the reality star on and off from July 2007 to March 2010. “I haven’t been worried about anything else or on anything in the past. Just the present and the future.”
Similarly, Reggie didn’t hear from any of the Kardashian clan when he welcomed his first child into the world.
“I haven’t spoken to them,” he said. “I’ve just been focusing on my little girl and my family. That’s it really. I’ve been enjoying my life and this opportunity. All my focus has been on that.”
