Britney Spears left her hotel, the Mandarin, in London today to head off on the rest of her Circus tour.

The singer has been staying there for the duration of her UK appearances, even driving the 200 miles back to London after her Manchester performance rather than staying up north.

Her two children have been staying nearby with their father Kevin Federline.

He was spotted taking them to London's Hard Rock Cafe for dinner last night.

Kevin apparently agreed to come on the Circus tour so that Britney does not have to be away from her children for too long.

Whilst in the UK Britney has treated them to toy shopping at the world famous Hamley's as well as a visit to London Zoo.

She is next due to perform in Dublin for two nights before heading off to France in July.
