It's no secret that Lady Gaga loves to have a good time.
Earlier this month, Mother Monster had a sleepover with fellow party girl Lindsay Lohan at the Chateau Marmont in West Hollywood and decided to share some photos on her website from the night.
A source told X17 Online: '[They were] watching old movies and playing board games [at the] slumber party. The three of them had dinner in the garden on Tuesday night at Chateau, and then Lindsay and Gaga ran upstairs to play dress up and came down in different outfits.'
The two proceeded to post insider tweets to one another with Gaga saying, "'@lindsaylohan when you ordered a cucumber and a knife to the bar last night i thought your were gonna perform a vasectomy #justaskinnyb***h," to which Lohan replied: '#skinnysnack1 @ladygaga hahaha.'
Peep their slumber party flicks below.
