The show most definitely went on for Mother Monster this weekend.

Lady Gaga pulled a Bieber during her concert in Barcelona, vomiting three times within the span of a few minutes while performing "Edge of Glory." (Justin Bieber faced similar on stage embarrassment last week in Arizona, when he threw up during his Glendale show.)

Despite her shaky stomach, Gaga, 26, barely missed a beat during her routine, picking right up where she left off after getting sick.

Post-show, the pop star took to Twitter to joke about the embarrassing incident.

Posting a YouTube clip from her soon-to-be-infamous number, she wrote, "Was praying nobody saw but actually it's quite a good laugh if you need one!"
