Tired pop princess Britney Spears has cancelled the Far East leg of her Onyx Hotel Tour, because she is suffering from exhaustion.

The Toxic singer, 22, has cancelled the July dates in the Far East because she is too tired to stay on the road.

The blonde superstar will play her last European date in Dublin on June 6 and then return home to America.

The source adds: "Britney also wants to spend more time with her new boyfriend Kevin Federline."
