YOUNG HOLLYWOOD TV
And the holiday turned from bad to worse for Bradley Cooper when his then-girlfriend called him up - and dumped him over the crackly phone line.
He tells BBC Radio 1 host Fearne Cotton, "The worst one (relationship experience) was I was dumped overseas on a bad line of a telephone. I was in Peru with an oxygen tank because I hadn't acclimatised properly.
"I was being dumped... it was done like with a delay. (She said), 'I'm happy on my own'. 'What, okay...' It was the worst."
But Bradley Cooper, who is currently single, has no hard feelings towards his ex, adding: "She's a sweetheart though."
