United Kingdom, Feb. 4 -- Ariana Grande is "missing a couple of years" from her life.

The 31-year-old singer-and-actress admitted she has a major memory blank in her past and can't remember a lot about a certain period of time.

Ariana was talking to host Will Arnett on the 'SmartLess' podcast and the host recalled when they both appeared on a "weird" UK talk show together.

But the 'Wicked' star admitted she had no recollection of the appearance and said: "I'm missing a couple of years. I'm super serious from that time. I'm literally missing a few years."

Will then quipped her behaviour had been "disgraceful" on the show, but then added: "No, you were great."
