CHICAGO — It’s no “Maury” paternity test, but a recent video declaring who LeBron James’s real father is will leave the NBA star befuddled and awestruck.

As it turns out, it’s Chicago Bulls star Jimmy Butler.

Just kidding. Jimmy Butler isn’t LeBron James’s dad. That would be difficult since Butler is five years younger than James.

But arithmetic and biology didn’t stop rap star Froggy Fresh from declaring Butler’s fatherhood in a relentless new music video.

In the bizarre amazing clip, Fresh (or should we say Froggy?), along with two of his friends, lauds Butler and proclaims his angst for James and the Cavaliers while sporting a Bulls jersey from the 1990s.

“I aint gon’ lie: LeBron, you’s a baller,” Fresh proclaims, “but Jimmy Butler is your father.”

It goes on pretty much like this for three and a half minutes.

It’s no surprise one may want to praise Butler, who is coming off the NBA’s Most Improved Player Award as the Bulls seek a spot in the Eastern Conference Finals (while looking to oust James in the process).

Fresh is no stranger to the YouTube rap game. His 2013 hit, “Dunked On,” has more than 8 million views.

The new video was uploaded Saturday and already has more than 150,000 views.

The series between the Bulls and Cavaliers is tied 2-2, after a James buzzer-beater downed Chicago in Game 4.
