As it turns out, fans of the "Waterfalls" group have already raised more than $122,000. The group hopes to raise an additional $28,000 by Feb. 19.
"A BIG Special THANK YOU 2 @katyperry for her pledge to our #Kickstarter Campaign!" Tionne "T-Boz" Watkins wrote on Twitter. "Your awesome!"
Lucky for Perry, she may not have to wait too long to hear the sweet sounds of TLC. After all, the group's tour kicks off May 1 in fabulous Las Vegas.
When chatting with E! News, New Kids on the Block couldn't help but reveal some of their favorite songs from the ladies.
"'Scrubs' is my favorite," Jonathan Knight gushed after being persuaded by Alicia Quarles to tell the truth. Joey McIntyre added, "I mean, ‘Ain't 2 Proud 2 Beg' was like the one that set it off and just exploded. I still love that one. That's my favorite."
And if you are hoping to see the New Kids collaborate with TLC on the same stage, you may just be in luck.
"We're going to come out on some of their [songs]," Rozonda "Chilli" Thomas teased to E! News. "We're going to study [their dance moves] every day and then we are going to pop up."
They are totally going to do "Step by Step" together, right? Oh, we can't wait for this summer!
