The latest series of the USA's 'Celebrity Apprentice' has experienced its fair share of entertainment, but last night's episode saw Meatloaf completely lose his nerve. 

Tension between the 'Bat Out Of Hell' singer and actor Gary Busey has been building with each show, and when he noticed that some of his art supplies were missing and Busey had them he finally snapped, yelling:

"You look in my eyes, I am the last person you ever..."

"You'll be in the hospital in about four minutes"

Following the very public outburst, Meatloaf offered a sincere apology to Busey, which he accepted, and told the cameras:

"I am so embarrassed by it,”

“Nothing ever gets solved when people do that. I’ve been beating myself over it all day.”
