The eccentric star posted a picture on her Twitter account last night of her in bed, clutching a monkey, with a sad expression plastered across her face.
She accompanied the snap with the caption: “Chipmunk Cheeks Wisdom Teeth out before tour. I can’t eat. I’m gonna put some meatballs in a blender. (sic)”.
Lady Gaga had informed her followers earlier on in the day that she had undergone the operation and was on medication to control the pain.
She tweeted: “Wisdom teeth out. P-p-Percocet p-p-Percocet (sic)”.
Meanwhile, the blonde beauty is determined to look her best at all times and recently admitted to using facelift tape as part of her morning ritual to pull her skin back on her face and neck to give her a more youthful appearance.
She said previously: “When I have my wig cap on and I’m taping my face, it’s a sort of meditation for me. Every day, it starts the same way. It’s like a mantra.
“I wash my face, I pin my hair back and put on a wig cap and I ask, ‘How am I going to form my eyes today with this tape? How will I pull back my neck with tape?'”
