The 'Breakaway' hitmaker was left baffled when she discovered "five to six big boxes of jewellery" in her handbag, so called her assistant to find out where they came from and was stunned to discover a series of events had taken place which she had no knowledge of.

Speaking to Kaley Cuoco on her own 'Kelly Clarkson Show', she said: "I was at CVS filling some prescription because I'd had dental work done the day before.

"And I look in my bag and I have all these jewellery boxes and I'm like, 'What the hell?' Like I have literally five to six big boxes of jewellery in my bag. And I'm like, 'Did I like rob someone's house?'

"I called my assistant and was like 'Dude, who's jewellery do I have in my bag?' And she was like, 'Well we went shopping, after rehearsal with the band, we went shopping and then we went to dinner.

"I had a full night completely with eyes open walking around that I don't remember."

"My band's laughing because I had rehearsal with them and I was sitting in a chair with sunglasses on and I go into the mic, 'That ain't my song.'

"I was so high from the dentist!

"I went to my friend's house, don't remember seeing the house."

The 'Big Bang Theory' actress joked she was keen to try whatever Kelly's dentist had given her.

Kelly said: "I didn't remember one bit. All of that is from what people told me... My question is, what did the dentist give me?"

Kaley quipped: "Wow! And where can we get it?"
