Angela Rayner has admitted she is known as "The Vape Dragon" by her children for her incessant use of electronic cigarettes.
The Deputy Labour Leader opened up on her habit for puffing on the vapor device at the Edinburgh Fringe Festival where she also spoke about her love for raving and unhealthy food.
Speaking to the comedian Matt Forde Rayner said: "I was ashamed the other day because I got three bottles of wine and eight packs of Juul2 vapes and that was it, that's all I had in my basket and I did actually think 'I need to put some fruit in there'."
The Ashton-under-Lyne MP added: "Vaping is probably really bad for you and I will find out one day, but yeah I enjoy a good vape."

Rayner is known for having a public image that is almost the complete opposite to that of her boss Sir Keir Starmer.
The party's deputy leader said that while her counterpart was a bit like a civil servant, she was far more relaxed, "more bombastic and in your face".
The Labour representative joked she had just recently returned from a holiday in Spain where she went on a round-the-clock rave.
She explained how she had started drinking in the middle of the afternoon and didn't go to bed until the sun was up the next morning.

"The girls I was raving with are half my age, and I was like 'I'm a grandma'," she said.
"I was proud of that. 4pm I started, and I got home at six o'clock in the morning when the sun was shining and I was like, 'Yes, I can do it'."
She added: "You've got to go with the music, the vibes.
"You've got to be in the moment and it takes you."
Rayner said she binge-drank vodka and often uses the spirit when she to make her favourite cocktail when she wants to "let my hair down at home".
She outlined how she makes a "lethal" cocktail called Venom which consists of a bottle of vodka, a bottle of Southern Comfort, ten bottles of Blue WKD and a litre of orange juice.
She said: "If you're ever having a crowd of you at home get that out and everyone will have a good time.
"I invited my two youngest kids' headteacher from primary school and he had to take his wife home because she'd had some Venom.
"One of my local councillors, I found her curled up in the dog's bed with the dog."
