Lil Baby has reacted to Young Thug's father, Jeffery Williams Sr., telling him to stop dissing Gunna over snitching allegations in his son's RICO case.

Williams Sr. spoke about the 4PF leader to journalist Infamous Sylvia.

"He need to shut the f*ck up, 'cause he don't know what's going on," he said "He going off a what he heard. Ask Lil Baby has he ever come to a court date. That's what I want y'all to ask these goddamn rappers and these bloggers with this snitch sh*t."

Lil Baby responded by writing "IFKYK," which stands for "if you know you know."

He then deleted it.

So, what do you think Lil Baby knows?
