Los Angeles: Singer Britney Spears came up with a strong response after media reports alleged she has 'amped' up on caffeine and energy drinks.

Britney, writing down a long Instagram post, said: " My mind gets busy and sometimes that can be an easy target to mess with 🙄 …. Anyways, I’m sticking to watermelon juice, which is the weirdest thing ever but I was told for years I can’t have coffee and now that I can it’s my pride … I can’t even look at it !!! And green tea 🍵 is my prized possession !!! You clever little turds 💩😂 … Sorry but I never stay up late with Red Bull !!!"

"It is absolutely the worst drink ever … I make jewelry, candles and doll clothes … Okay, so what ??? I may be a loser but I do what makes me feel most alive and gives me interest but I don’t like people in media bullying me and saying hateful things," she said.

Recently, TMZ reported Spears drinks caffeine drinks by the gallon.

Sources with direct knowledge tell TMZ, which has produced a documentary that will air Monday, Britney guzzles Red Bull, Celsius, coffee, and dandelion tea almost nonstop.

"We're told she consumes so much caffeine, she'll sometimes stay awake for 3 consecutive days," the US website reported.
