The pop superstar, who is reportedly back in the arms of her ex-boyfriend Robert Ackroyd, bares her soul in a revealing new interview with US comedienne Chelsea Handler.Speaking about her former husband Brand, she insists that their marriage seems very distant, explaining: "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**t to get your grips on life and figure out what the next boundaries in your love life are going to be."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 teammate."And it appears she may have found that, at least for a short time, in ex-boyfriend Mayer.Perry tells the July issue of the magazine: "I have a lot of respect for (John) still."The singer split from Brand at the end of 2011, and she ended her relationship with Mayer in February.
