Katy Perry has said it feels as though her marriage to comedian Russell Brand feels like "a hundred lifetimes ago".
The singer, who is reportedly dating her ex-boyfriend Robert Ackroyd again following her split with John Mayer, told chatshow host Chelsea Handler, "It feels like a hundred lifetimes ago, so it's like digging up an old grave.
"A lot of therapy has happened and a lot of understanding and growth . . . Sometimes you have to go through all this s*** to get your grips on life and figure out what the next boundaries in your love life are going to be."
She added, "You have to go through the mud in order to find that peaceful place. In the long run, it was necessary for me to have more of a team mate."
