Most singers miss performances by using the lame "exhaustion" excuse. But not Erykah Badu -- she still made a SXSW gig last night in Austin even though an alleged stalker had barricaded Erykah inside her home.

Badu used the all-powerful Twitter to update fans, saying "Police just apprehended a stalker in front of my house. Stay tuned to details."

Erykah went on to say the woman had been outside of her house multiple times -- and she had "several misc. items spread out in the grass. Blue shutters, a rabbit, a tucan and a sketch book."

The lady was "pepper sprayed and cuffed" by cops -- and filling out the police report made Erykah late for the gig.
