00:49 GMT, 3 July 2012
As her marriage to Russell Brand crumbled, Katy Perry was ever the professional, performing to thousands of fans on her concert tour.
But in her new documentary film Part Of Me, the singer is seen breaking down in tears and unable to speak as she struggled to comprehend her relationship problems.
The movie, which was filmed over her 2011 tour, saw the singer and comedian initially happy and in love.

But as the tour continued and they spent increasingly amounts of time apart, Katy has allowed the cameras to capture her despair.
As well as showing that she was the one making the most journeys to visit her husband, the film also reveals their different attitudes to family.
While Russell, 37, appears to be looking forward to parenthood, at 10 years younger and with only a few years of success behind her, Katy isn't quite ready.

Another scene shows an exhausted Katy on a plane asking one of her entourage when her next break in the tour is so she can fly and see her husband.
She looks distressed when she is informed she won't be able to see him for another 18 days.

Reflecting on her documentary, Katy said this week: 'Every
ten days or so I would put everybody (on the tour) on pause for three
or four days so I could go back and re-charge and see to my relationship
and give that time, which was very intense for me because the show was
still on the road.
'But I made that sacrifice because it was important for me and I had made a commitment at that time.
I had to fly in on the day of the show, completely jet-lagged and
feeling like I had been hung by my ankles, and have to go on stage. But
it's like I pushed a button when I walked out (on stage.'
In another sequence, Katy receives a text from Russell mentioning their future children, to which she says: 'I will be a mother when I decide to be a mother, but not right now. A baby can't have her baby.'
A second text then prompted the singer to break down in tears.
