Watch Drew McIntyre lose it in X-rated rant after CM Punk costs him title match as he lashes out at ref and commentators

WWE superstar Drew McIntyre went berserk after his controversial loss at Clash at the Castle and exploded with an X-rated rant.

McIntyre, 39, challenged WWE World Heavyweight Champion Damian Priest at the OVO Hydro in Glasgow on Saturday after he controversially lost the title at WrestleMania 40.

The Scottish bruiser won the belt in April after beating Seth Rollins but was attacked by CM Punk and Priest cashed in his Money in the Bank contract to pin him five minutes after his title triumph.

The British wrestler was determined to win the world championship back in his homeland in front of 11,000 compatriots during an emotional weekend that saw his wife undergoing emergency surgery.

McIntyre had Priest beaten as he floored him with a devastating Claymore.

But there was no referee for the pinfall as the official was knocked off the ring apron moments earlier.

Then CM Punk made a shocking return with a referee's black-and-white striped shirt on him and taunted The Scottish Terminator by refusing to count to three.

pushed Punk into the turnbuckle and that was when the American legend delivered a crushing low blow.

Priest recovered and connected with the South of Heaven Chokeslam to pick up the controversial win.

WWE released footage showing The Scottish Warrior going crazy after the bell as he delivered an X-rated rant towards the referee and commentators.

McIntyre grabbed the referee by the shirt and was heard yelling: "Where the f**k were you?"

The official appeared to respond: "I got knocked off the ring, I didn't see anything."

McIntyre then grabbed commentator Corey Graves by the neck as the American yelled: " I didn't do anything."

The three-time world champion proceeded to confront fellow British great Wade Barrett with whom he exchanged heated words.

As the ex-WWE Champion walked away he was heard yelling: "You piece of s**t.";

This was the second time McIntyre fails to win a world title in the UK due to outside interference.

The Brit had Roman Reigns beat for the Undisputed WWE Universal Championship two years ago at Clash at the Castle in Cardiff but Solo Sikoa got involved and helped his cousin win.
