"Shake It Up Tonight" is a 1981 hit single by Cheryl Lynn. Since the success of her debut hit, "Got to Be Real," the acclaimed R&B-dance track peaked at No. 5 on the Hot Dance Club Play charts and it also scored number 70 on the Billboard charts. "Shake It Up Tonight" appears on Lynn's LP In the Night. The b-side is "Baby," written by Cheryl Lynn and Ray Parker Jr. The ready-made disco song was a moderate success, completely failing to score UK charts.
