Pop superstar Lady GaGa will only eat food prepared by one British chef when she visits London next. The "Born This Way" singer will travel to the United Kingdom in upcoming weeks on a promotional tour. While she is in the country, Lady GaGa will dine on food specifically prepared by Angela Farmer, a sous chef in the lavish Lanesborough hotel.

"Gaga won't eat anything unless it's been specifically prepared by Angela which means meal times can be a bit of a nightmare when she's on promo duty," a source told British newspaper The Mirror.

Lady GaGa is on a strict lean protein diet. The star eats five small meals a day and only drinks tea, water, coconut milk and sugar-free drinks.

Angela Farmer prepares healthy food just the way Lady GaGa likes it. The singer often eats the chef's meals on the go. "Gaga specifically loves Angela's canapés of serrano-wrapped shrimps and her monkfish skewers, so quite often these are wrapped up and served as an on-the-road packed lunch," the source shared.

The Lanesborough is confident in their cuisine. The reputable establishment is happy to accommodate special requests like Lady GaGa's from time to time.

"Angela does work here and is one of a team of sous chefs working with executive chef Paul Gayler," a Lanesborough spokesperson told the newspaper.

"We are known for our innovative cuisine so it sometimes happens that guests ask for a particular chef they like," the spokesperson added.
