Pop superstar Lady Gaga has been joking with her crew on Twitter about the progress of her forthcoming new record, 'ARTPOP'.

Earlier this evening, her make-up artist Tara Savelo sent out a public message that explained she was sat watching Gaga writing new music:

"nothing like watching @ladygaga in her waspy white sweater and brown hair write the hardest marijuana record of all time. #maryjaneholland."

Upon reading this, the 'Marry The Night' superstar replied with: "well i was going for a more stoned disney princess kinda vibe. not so much?"

Following this brief exchange, sound engineer Dave Russell shared a photo of Gaga in the recording booth and she joked: "Aren't you suppose [sic] to be recording my flawless vocals. stop photographing me creepo."

Gaga also shared her thoughts on the leaked naked photos of Prince Harry that have been circulated online today (August 22) and tweeted:

"HOLY MOTHER HARRY LOOKS FIT. hope no ones mad at him for that, I'm certainly not #RoyalsArePeopleToo. but truly f*ck off to whatever shitty friend took those picture and leaked them."
