Lady Gaga tweets a photo of her bruises

Lady Gaga was feeling "woozy" after sustaining a concussion during a concert in New Zealand. The pop star was performing her Born This Way Ball show in Auckland over the weekend when a back-up dancer knocked her in the head with a pole during the song "Judas."

The star stumbled around and rubbed her head before exiting the stage. However, she returned to perform the rest of the show. "I want to apologize," she told the crowd. "I did hit my head and I think I may have a concussion. But don't you worry, I will finish this show."

On Tuesday (June 12), she tweeted an update along with a photo of her bruises.

"Thank you so much for all the thoughtful messages. I feel a bit woozy but a little better everyday. Very happy to be in beautiful Australia," she wrote. "Emerging from hours of sleep. Still remiss if I should go outside, with this clonker I may be of questionable styling."
