TLC's Kickstarter campaign to make a new album is $5,000 closer to its fundraising goal ... thanks to none other than Katy Perry

According to our sources, the "Roar" songstress is such a big fan ... she dug into her own pockets and shelled out 5 grand for the cause. 

One of the perks for a $5k donation is a slumber party in L.A. with T-Boz ... so we could be in for some epic selfies.

As of this posting, the girls are still a little more than $44,000 shy of their $150,000 goal.
