London, Jul 14 (IANS): Singer-songwriter Jessie J says she has given up on alcohol because it leaves her lethargic. She was worries it would ruin her career.

The 25-year-old admits that she hasn't had a drink since Oct 15, 2012.

"Even one glass of wine every now and again used to just make me tired. Made my skin tired, made my voice tired. How crap would people's day be if I turned up hungover and miserable and not wanting to talk?" femalefirst.co.uk quoted Jessie as saying.

The singer insists she is no diva and prefers to do household chores herself on her days off work.

"I do my own washing, I've got to empty the dishwasher, I need to clean my fridge and love having ironing to do. I'm normal, I go into my house and I want to tidy up, hang pictures on the wall and the boiler man's coming. I've got to take my dog to the vet," said Jessie J.

"That fills my day off and then I need a day under the duvet to watch films and actually rest my body. You've got to work hard if you want this," she added.
