The famously pro-pot 24-year-old singer — who revealed she is “completely clean” from drinking and drugs in a May Billboard cover story — shared some throwback photos clinking glasses with her older sister.
“Current Mood: Happy B-Day @brandicyrus & congrats on your show launch! BIG day! Love you soooo much! 🦄PS as you slide thru these next few photos it will become very clear as to why I no longer drink! LOL! (Or maybe why I should start again…. J/K 🐬) Always the best time when I am w my big sis! Xoxoxoxoxoxox,” Cyrus captioned her court side photos, where the look-a-like sisters are captured drinking, laughing and playfully grabbing each other’s faces.
Introduced by her father Billy Ray Cyrus and her sister Noah Cyrus — who joked it was Miley’s “first time [appearing] in years with pants on” — the singer let her sultry voice do the talking, in an unusually stripped-down performance.
