Tish Cyrus has confessed she got "too high" at one of her daughter Miley's birthday parties.
Now sober, the podcaster admitted she made several errors of judgment in her hard-partying years.
Appearing on the Boyfriend Material with Harry Jowsey podcast, Tish, 58, revealed she had accidentally consumed too much cannabis at one of Miley's birthday parties, held at Beachers Madhouse in Los Angeles.
"Miley would have parties there and it was a whole thing, but this was actually before I smoked, and I ate some brownies at the party," Tish told Harry, 28.
After taking herself home, Tish woke up two hours later to realise, "everything was spinning and I was coming freaking unglued", she recalled.
"I actually called Miley and I was like, 'Oh my gosh, Mile. I feel so weird and so sick. I need to go to the emergency room. You have to come get me right now'."
Also being interviewed was Miley's sister, Brandi, 38, who chimed in to remind their mother about another incident that had taken place in Denver, Colorado.
"You were so stoned you couldn't speak," Brandi revealed. "You were mute, and then you tried to get yourself back to my apartment and I had to call someone to let you in because you literally weren't speaking."
