NFL superstar Keyshawn Johnson confronted Justin Bieber about what he saw as speeding through their gated Calabasas, Calif., community just before police were called Monday night.

A representative for the former Super Bowl champ told ABC News that Johnson scooped up his children playing outside his house when he heard what sounded like a race car streaking past.

Johnson then jumped in his own car and followed Bieber's white Ferrari to the singer's home.

There, he knocked on Bieber's car window, but the singer refused to get out, according to Johnson's representative. Bieber's security personnel then tried to block Johnson, who finally grabbed Bieber and confronted him about his driving.

However, Bieber told Johnson that he was not the one behind the wheel, Johnson's representative told ABC News.

The singer's representative declined to comment, but a source close to him said it was his pal, Tyler, the Creator, who was driving.

READ: Justin Bieber Investigated for Reckless Driving

Bieber is under investigation for driving recklessly in his California neighborhood after two people spotted someone they believed to be the star behind the wheel of his white Ferrari, driving "extremely erratically at high rates of speed" Monday night, Steve Whitmore, a spokesman for the Los Angeles County Sheriff's Department, told ABC News Radio.

"Two witnesses have already come forward and filed a report," Whitmore said. "We're investigating [this] as misdemeanor reckless driving and planning on presenting [the case] to the DA."

Apparently, Johnson is not the only NFL star who thinks Bieber drives too fast.

NFL Hall of Famer Eric Dickerson chimed in on Twitter, "I live in Calabasas too and @ justinbieber needs to slow his a** down."
