Elvis Presley tells new documentary "no amount of money" could make him feel "any satisfaction inside"

The King confessed that superstardom left him feeling "lonely" and "unfulfilled"

Elvis Presley said there was "no amount of money" that could make him feel "any satisfaction inside" in a new documentary.

The King opened up about the downsides of fame in an interview with American TV journalist David Frost back in 1968.

The chat is part of a new documentary series called "The King" airing on the US cable channel HBO.

In the documentary, Elvis spoke about the pressures of superstardom, saying it left him feeling "lonely" and "unfulfilled".

"There's no amount of money that can buy you happiness," said Elvis.

"I've got everything I could ever want - money, fame, success - but I'm still not happy.

Money can't buy you love

Elvis's words echo the sentiments of many other celebrities who have spoken about the downside of fame.

In 2013, Justin Bieber told the Hollywood Reporter that he was "lonely" and "unfulfilled" despite his success.

And in 2016, Lady Gaga told Vanity Fair that she had "cried every night" for two years after the release of her album "Born This Way".
