To make matters worse, it was on purpose!

Always the performer, Lady Gaga got artist, Millie Brown, to puke on her while she sang her single, ‘Swine’.

The performance took place on the Doritos #boldstage at SXSW in Austin, Texas.

Millie is known for her unique works of art that she creates by drinking coloured milk and puking it up onto canvas.

Stomach churning!
