IT TURNS OUT that exploding meat loaf is not a pretty sight – particularly when the Meat Loaf in question is a riled-up rockstar getting heavy with the profanities.

The meltdown took place on last night’s episode of the American version of Celebrity Apprentice, when Meat Loaf (born Marvin Lee Aday) accused actor Gary Busey of stealing art supplies during a fundraising challenge.

As the teams sorted out their paints and sponges, Meat Loaf started looking around, before shouting at actor Gary Busey:

I  bought those motherf****** sponges!

“I’m f****** sick and tired of you, mother f*****!” he continued, as singer Mark McGrath got between the two men in an attempt to prevent fisticuffs.

As Busey explained himself, Meat Loaf shouted:

Bull****! You don’t wanna f*** with me – you look into my eyes; I am the last person in the world you ever wanna f*** with! You understand me?

According to ABC News, Meat Loaf later apologised, saying he was “embarrassed” and upset by his behaviour, and was “truly sorry”.
