“We hit it off, made a new friendship there, and we had a lot of fun,” the country singer tells PEOPLE

Drake Milligan has been itching to stretch his acting muscle since portraying the legendary Elvis Presley in the CMT series Sun Records. But never did he picture stretching that acting muscle alongside Cheer star Gabi Butler.

“I had never met Gabi before,” says Milligan, 25, in a recent interview for PEOPLE. “We hit it off, made a new friendship there, and we had a lot of fun. Gabi is a natural. She seemed really comfortable in front of the camera and was just able to really show off all the little emotions. She looked great on camera too.”

The two also came out of it with a music video for Milligan’s new song “What I Couldn’t Forget.”

“One of my favorite parts about this video is I got to have all my friends in there,” explains Milligan of the music video shot over two days in Nashville and now premiering exclusively on PEOPLE.  “Besides Gabi being there, one of my friends from Texas came in with me and he was all over the videos. And everybody in my crew, people that work with my team, my social media team, my tour manager, all my band and his friends I have around Nashville came in and we used them as the extras in the video.”
