Tony McGregor hailed his son and Dee Devlin following the couple's appearance at the MTV Video Music Awards.

UFC star Conor was involved in a scuffle with Machine Gun Kelly on the red carpet in New York on Sunday night ahead of the awards bash.

Describing the couple as 'rock stars', Tony said his son was 'global' as he watched the former two-weight champion present an award to Justin Bieber.

The former taxi driver shared a number of videos from the awards ceremony to his Instagram story on Monday night.

On the bust-up with the rapper, Conor insisted “nothing happened” and said he didn’t even know who Machine Gun Kelly was.

The fighter told Entertainment Tonight: “Absolutely nothing happened.

“I don’t know. I just showed up and I don’t know.

“I don’t even know the guy to be honest with you.

“Nothing happened with me, I only fight real fighters, people that actually fight, you know what I mean. I certainly don’t fight little Vanilla Ice white rappers.

“I don’t even know the guy. I don’t know anything about him, except that he’s with Megan Fox.”

US website TMZ claimed the clash happened after McGregor asked the musician for a photo but was shunned.

Sources told the publication that MGK then pushed Conor who stumbled and spilled his drink, before reportedly throwing what was left of it at the singer.

The clash was captured by onlookers as McGregor appeared to lunge at the singer after a few choice words between the pair.

He didn’t appear to be able to get his hands on the star as security pulled him away.

MGK was also quizzed about the alleged altercation but refused to comment.
