Sources with direct knowledge of the event tell us AK is scheduled to take the stage Friday at the State Farm Arena in Atlanta for the Migos rapper's sendoff. It's unclear how long Alicia will perform, or what exactly she might be singing ... but we do know she'll be there and mic'd up to sing.
She also posted a tribute to Takeoff after his shooting death, saying ... "This is too much. It's like every day. RIP Takeoff. Sending light to your family and loved ones. We are losing too many too soon!!"
