They've never confirmed the reasons for the dissolution of their marriage in anything but the vaguest terms.

But all that could change in the wake of a new film that will feature Katy Perry's doomed union with Russell Brand.

The 27-year-old opened up to Ellen on her show about her new film, Part of Me, and how she decided to show a realistic account of her life in the feature, including her relationship with Russell.

Katy's news comes just a week after Russell, 36 , told Ellen that he still loves his estranged wife.

The chat show host asked Katy about the 3D documentary, saying to her, 'of course you got married during that time and that didn't turn out to last, is part of it still in there?'

Katy told Ellen: 'I thought it was important to show everything in between.

'I think sometimes people think that were perfect and we know were not perfect, at all.'

'I think its important to start breaking down the idea that to achieve your dream you always have to be perfect or flawless or live in some kind of fantasy world. So thats why I decided to put everything into the film,' Katy said.

'In the most tasteful way. But mostly its about how I go there and the ride along the way which can be bumpy but mostly it was extremely fun.'

Some reports suggested that Katy had cut Russell from the footage, but this interview finally lays those rumours to rest.

The couple have been granted go ahead for a divorce but it will not be finalised until July, because California law requires a waiting period of six months.

They split just two months after their first wedding anniversary.

Katy was said to have been 'blindsided' when Russell filed for divorce just after Christmas.

The move came after the pair enjoyed separate holidays over the festivities, she in Ha! waii and Russell in his native England.

The pair have both moved on, Russell has been linked to Brazilian artist Oriela Medallin and David Hasselhoff's ex Anouska De Georgiou, while Katy has had flings with Baptiste Giabiconi and Florence + the Machine guitarist Robert Ackroyd.
