Mike Gundy and Justin Bieber now sharing ringtones

Before this weekend, it probably never would have made sense to have Mike Gundy and Justin Bieber in the same sentence.

But apparently there is a mutual admiration among the Oklahoma State coach and teen singer.

It was revealed Sunday that Bieber has the famous Gundy quote "Come after me. I'm a man. I'm 40" as his ringtone.

"I watched the video. I thought it was funny," Bieber said, "so I set it as my ringtone for everything."

On Monday afternoon, Gundy was speaking with reporters when his phone when off and the ringtone was playing the Bieber hit song Baby.

When asked about the coincidence, Gundy replied: "I changed mine last night. I figured if that if he was going to use my ringtone, then I should start using his ringtone."
