Britney Spears, who is rumored to be planning to flee California for a new life with sons Sean and Jayden, is planning a move across the Transatlantic. Brit has her heart set on moving England-and has even started to practice her British accent.

“She thinks her only hope is to move to London for a fresh start.”

“She is so scared about losing her boys that her mind is racing trying to think of how to keep them.”

But a Britney pal believes the ‘I Got That (Boom Boom)’ singer won’t fit in on the West End:

“She doesn’t have a clue how to write a cheque.”

“She honestly thinks she can arrive in London and blend in with the locals.”

“She thinks that double-decker buses are tour buses. And she doesn’t even know what the BBC is.”

“How does she think she could pull off moving to another country?”

Brit’s planning to high-tail it to Las Vegas and then board a private jet to the UK in the middle of the night, the friend claims.

“Part of the problem now is that she doesn’t have anyone around to help her make the best decisions….She is convinced she can win custody.”

Their custody case is due to be heard in Los Angeles Superior Court on September 17.
