Intense: Lady Gaga gave fans a vulnerable glimpse into her everyday life in the latest emotional teaser of her new Netflix documentary Gaga: Five Foot Two

At several points in the clip, she is seen appearing to smoke marijuana - including in the car and while leaning against a wall.

Resting her cowboy boots against the car dashboard as she lights up, she later drawls: 'I always get stoned in Grandma's car.'

She also mingles with her famous friends - wrapping singer Florence Welch into a warm hug before laughing away with producer Mark Ronson in a studio.

Gaga later gives close friend, Donatella Versace, a loving hug after the fashion designer flew by private jet to support her ahead of her SuperBowl show.

Another scene sees the Applause hitmaker crouching on the floor in a pair of hotpants and a white crop top.

Gaga - who has spoken openly about suffering from chronic joint and hip pain - is later seen on a hospital trolley, wincing as she's injected with anaesthetic.

'I suffer from PTSD,' she said on the Today show on NBC. 'I've never told anyone that before, so here we are.

'But the kindness that's shown to me by doctors as well as my family, and my friends, it's really saved my life.'

Meanwhile, Lady Gaga - real name Stefani Germanotta - gave an explanation behind what went wrong between she and pop icon Madonna in a previous teaser for Five Foot Two.

'The thing with, like, me and Madonna, for example, is that I admired her always. And I still admire her no matter what she may think of me,' the blond tells a friend as they sit on the floor.
