THE UNDERTAKER and WWE chief Vince McMahon BOTH broke down in tears as they openly told of their special relationship in a heartbreaking interview.
The 76-year-old wrestling boss has known the Phenom for more than 30 years, and the pair struck up a very close friendship.
He is known as a hard, no-nonsense man, who rarely shows his emotional side, and has barely been seen on camera in recent years.
But McMahon had to stop an interview while filming The Undertaker's 2020 documentary on WWE Network called Last Ride.
He was clearly upset when asked about what Taker – real name Mark Calaway – means to him on a professional and personal level.
The legendary owner cut off the doc being filmed, and said “I can't do that” - as tears formed in his eyes.
McMahon – talking in the second episode of a five-part series – went on to say: “Undertaker, Mark Calaway, is the most loyal performer I've ever dealt with.
“He is the kind of man you'd want literally in the foxhole with you."
The duo became close in the mid-to-late 90s and early 2000s when the infamous Monday Night Wars with rival promotion Nitro occurred.
Many of the WWE's top stars jumped ship for more money and stardom, but Undertaker stayed loyal, something McMahon never forgot.
Calaway - who named his son Gunner Vincent - said: “I can't think of anyone more influential on my life, other than my father, than Vince.
“He'd be the first one to pat you on the back, but also the first one to kick you in the ass when you need it.
“I love Vince to death. I'd take a bullet for the man, honestly I would. Yes, he's my boss. He's my friend. He's been like a dad.
“He's been like a brother. He's been it all to me. I've gone through some really harrowing personal issues in my life.
“Kinda let them take over who I am as a person. The problems just became so monumental that I didn't really care about anything else.
“He was the one that basically sat me down in a chair and told me 'Mark, you need to quit feeling sorry for yourself'.
“There's no other person that could say that to me that I wouldn't have got up and knocked the s*** out of them.

“But it was Vince, and I knew it was true, and I knew where it'd come from.
“Tough love. That's what I needed, but not because he was my boss, but because he was my friend and he cared about me.
“He's an incredible man and a very important person in my life that's made me a much better man."
McMahon after 40 years in charge of the company.
