A clip of the pair from a few years ago leaked online last week, and it captures a wonderful and lively rendition of the friends singing Boyz II Men's "I'll Make Love to You," after enjoying a few beverages.
During an appearance on Australia's The Kyle O and Jackie Show on Tuesday, Oct. 29, the "Roar" songstress dished about the now infamous duet and her friendship with the Twilight babe.
"Well, there's the media for you, nothing is sacred, not even karaoke," the 29-year-old singer joked. "Yeah, no I mean, we were just hanging out and we have a lot of friends that we hang out, one of my best friends is a mutual friend of ours and we got wasted and did karaoke like people do."
"At least it shows you that we're like actually just friends," the pop star added. "We're like true friends."
And even though Katy and R.Pattz have never been an item, she understands that it can be tricky being friends with him without the rumor mill churning that you are linked romantically.
"It's like if you're a girl you can't be friends with that guy, that poor guy, I mean come on," she said. "I feel for him, I feel for him," she added with a smirk.
The clip, which was filmed at the Burbank, Calif., karaoke club Dimples a few years ago, finds Perry at one point sitting in the Twilight hunk's lap as they give it their best R&B spin.
More karaoke please, guys!
