It looks like Keith Sweat isn't staying up to date with his trap rappers.
Today, the R&B star took to Twitter to post a picture of himself and NBA Youngboy.
Unfortunately, Keith thought he met 21 Savage and captioned the now deleted post as so.
@21Savage and #SWEAT
After getting clowned on, Keith changed the caption and turned off the comments.
It's ok Keith, just don't mistake Thugger as Lil Wayne and we're good.
