Britney Spears has reportedly been warned to stay away from Lindsay Lohan during her time in London.

The star kicked off her eight-show run in London at the O2 Arena last night - and Lindsay arrived in the UK earlier in the week.

A source told the Mirror: “Lindsay is a bit of a loose cannon. She landed in London knowing that her ex Sam Ronson and Britney are in town.

“Britney’s camp do not want that type of attention.

“She and Lindsay used to be friends, but it was all about going out partying.

“Brit’s family are trying to steer her away from the every night extremes that Lindsay gets up to.”
