Adele performs at this year's Grammys
Adele had "a breakdown" when she started recording in America.
The 'Someone Like You' hitmaker was overwhelmed to team up with producer Rick Rubin for her album '21' because the studio they worked in, Shangri-La in Malibu, had previously been used by some of her heroes including Johnny Cash and Red Hot Chili Peppers.
She said: "The first day I had a breakdown. I lost it and started crying and had to go for a walk on the beach to sort myself out.
"After that, I was fine though I still had the odd moment.
"Between a take, Rick would talk to his engineer and say, 'Remember when we had this problem with Johnny Cash?' Then one day Kid Rock dropped by to do a vocal for something while I was outside having a fag. It all felt like an out-of-body experience."
Adele also admitted she "panicked" when stricken with writer's block on the road at a time she planned to pen the follow-up to her debut album '19'.
Enrique Iglesias in July 2010
Enrique Iglesias flew his plane before getting his pilot's license.
The 'Tonight (I'm Lovin' You)' singer was obsessed with aviation and couldn't wait to take to the skies himself, and got into the cockpit before he was officially qualified.
He said: "I shouldn't say this, but I bought my plane before I had a [pilot's] license.
"I was like that kid the Barefoot Bandit. He didn't know how to fly, but because he loved planes, he did it anyway."
Enrique - who is in a relationship with retired tennis player Anna Kournikova - also revealed he was devastated by the loss of one of his "best friends" when his dog passed away last year.
Asked what he always takes on the road with him, he said: "I have a picture of my two dogs, Lucas and Grammy. Grammy passed away in 2010. That dog was like a human - he would get sad when I packed my bags. It was like losing one of my best friends."
