Miley Cyrus has once again caused controversy and has well and truly cast off her Disney roots after straddling a giant inflatable penis at G-A-Y.

The singer was playing a surprise performance at the London hotspot last night and entertained fans that were cheering her on by straddling the giant prop beforewrapping her mouth around it.

She later presented a friend who was also at the venue with a penis shaped cake decorated with chocolate sticks.

The singer told the raucous crowd: "Everyone's gay. All it takes is one cocktail. And if that doesn't work, sprinkle something in their drink.

"That's what I always do."

The singer has recently recovered from an illness which left her hospitalised and forced her to cancel many of the US dates on her Bangerz tour.

She is now preparing to embark on the UK leg of the tour as previously planned.
