The "Fireworks" singer took to Twitter today to playfully scold her pal for failing to extend an invitation to her epic Saturday night romp at the strip club after RiRi instagrammed pics of the late-night fun.
"Ermm…I was in LA Saturday night…Should I be proud or offended I wasn't invited @rihanna #WHOISTHISDOPPLEGANGER," Perry posted on her micro-blogging page.
And of course, RiRi replied to her BFF, letting her know she wasn't in L.A.:
"@katyperry errm I wasn't! Lol! #miaminights howeverrrrr....I'll still let you spank me!," she cheekily fired back.
So naturally, the famous friends set a Twitter date to reunite and make up for missed time together.
Ladies, we're holding you to that promise.
