"I can drink 25 bottles of white wine in one night and I’ll be fine."

The 'Rolling in the Deep' songstress opened up to the audience of one of her recent shows in Las Vegas about her drinking habits.

“I don’t drink as much as I’d like to, but in two weeks I’m retiring, I’m going to become a day drinker.

“The thing is, I can’t really handle liquor in general.

“I can drink 25 bottles of white wine in one night and I’ll be fine.

“I will have a normal conversation with you.

“Three liquor drinks, and I am 25 sheets to the wind. I am heading to another planet.”

The 36-year-old previously revealed that she plans to take a huge step back from the spotlight once her Vegas residency comes to an end.

 “I have 10 shows to do, but after that I will not see you for an incredibly long time," she told her Munich crowd.

However, she admitted she will have to be careful about what she keeps herself occupied with.

 “I better find something else to do because if I don’t make any plans then I’m just going to become a drunk.”

“Tequila makes me aggressive,” she said.

“I’m ready to throw punches when I have tequila. It makes me f****ng vicious. I have hangover-anxiety for about five days after.

“I steer very clear away from tequila. I just can’t handle it, which is crazy because again because I’m a Brit and I can drink anyone under the table.”
