Bradley Cooper's movie star dog has become a diva

Speaking at a New York City Q+A for Is This Thing On?, Bradley said: "Charlie, it's his second film, everybody knows that. He was the dog in the movie A Star Is Born, he was Jackson's dog. He was only like three then, no probably like two. He crushed it. He actually won an award that year, we have it at home.

"He's so cocky now. He was unbearable."

Meanwhile, Bradley was named as People magazine's Sexiest Man Alive back in 2011 and his friend Dax Shepard revealed that The Hangover star thought that the publication was "pulling a prank" on him at first.

Dax said on his Armchair Expert podcast last year: "He genuinely thought when he was named Sexiest Man Alive that it was a bit - that People magazine was pulling a prank. He thought they were f****** with him.

"I'm like, 'You handsome son of a b****. You have no idea how horny everybody is for you.'"

Dax, 50, believes Bradley is proof that even the rich and famous suffer from insecurities.

The podcast host reflected: "I'm interviewing people who are either acclaimed academics or politicians or movie stars. They are very high-status people, and almost without exception, the beautiful people think they're ugly, smart people think they're dumb, the rich people feel like they don't have enough."

Bradley has daughter Lea, eight, with his former partner Irina Shayk and admits that becoming a father prompted him to change his life for the better.

He told the Armchair Expert podcast: "I'm not sure I'd be alive if I wasn't a dad ... I just needed someone to say, like, 'We're gonna drop this massive anchor.'

"I'm like, 'Why? We're speeding! I just got an upgrade on the boat, and I know where the wind's coming in.' They're like, 'No, no, no, there's a tsunami coming in, and you need an anchor and we're gonna drop it.'

"Because this is gonna dictate everything you do from now on. Your DNA is going to tell you that there's something more important than you."
