Lady Gaga has been practising how to speak like the British Queen for her new show, and is even dressing like the royal.

The singer is keen to make her upcoming tour dates in the UK extra special, and thinks speaking to her fans in an English accent would impress them. Gaga is determined to master the monarch's posh tones, and has been spending increasing amounts of time practising while at home.

"She's been copying the way the Queen speaks from online content. She loves all things British, especially the Queen. She wants to be able to do a really good accent for when she's over here on tour later this month," a source explained. "If she gets dressed up in regal attire, she feels like it helps her accent."

The 24-year-old has been testing her new speaking voice out on friends to get some feedback. She bumped into Sir Elton John at a recent benefit concert in New York, and even asked him for tips on how to pronounce British words.

Gaga is now convinced she has mastered the accent, so has started trying to trick her friends when she speaks to them.

"Gaga is trying it out on every available opportunity. She chatted to Sir Elton about various British elements - she can't get enough of the monarch," a source told British newspaper The Sun. "One thing she loves doing is prank-calling her friends to see if they can guess who it is."

The singer's obsession with the monarch is believed to have started last year, when she met Queen Elizabeth II after performing at the annual Royal Variety Show. The flamboyant star wore a red, PVC ruffled dress for her appearance, which saw her hoisted 30ft into the air to play a piano.
