In less than a month, Katy Perry's 3-D docu-concert, "Part of Me," will hit theaters across the world and give fans a look at the pop star's road to superstardom, including her divorce from husband Russell Brand. It's one of the more anticipated topics in the film, and it appears as if Perry has started to spill a little about how she coped with the fallout.

On Thursday, Perry visited the U.K.'s "Graham Norton Show" for a chat, and she discussed how she prevented any personal lows from affecting her extensive California Dreams World Tour.

"I love being onstage, and even though I went through some pretty tough times last year, I had to separate that because I know my problems are my problems and they are not the audience's problems," Perry told the talk-show host.

Always a true professional, Perry had a "show must go on" mentality, saying, "They are here to see a show and to be entertained, so I got on that lift, put a smile on my face and went up (onstage) with my t--s spinning!"

Perry hasn't given up on love either, as it's been reported that the singer rekindled her romance with Florence and the Machine guitarist Robert Ackroyd. After the television taping, the duo were spotted together walking the streets of London and getting comfy in a car. Back in May, Us Weekly reported that the [article id="1685522"]duo amicably parted ways[/article] after dating for a just few weeks.

Nonetheless, Perry is rolling with the good times, especially with the looming release of "Katy Perry: Part of Me" on July 5. Earlier in the day, the media darling took to Twitter to share her excitement over her surprise appearance at a fan screening for the Paramount film. "Had tons o' fun in London today at a surprise screening ... Wish I could sit w/ all of u when u see #KP3D," she wrote.
