Just last week Lady Gaga suffered a concussion while performing in Auckland, New Zealand.
One of her back-up dancers accidentally hit her in the head with a pole while she was singing "Judas." Since the show must go on, Mama Monster continued singing, even though she placed a hand on her head.
Later, she Tweeted to indicate an MRI had been done and she's going to be okay. "Went for an MRI. No harm from the concussion but it appears my brain is just water and a large floating jellyfish."
With a sense of humor intact, the "Born This Way" singer wrote to her dad on the social media site: “@germanottajoe i had them check my noodle. that was your fathers day present Il mio babbo!! I thought they were taking me to the zoo. TRICKS”
