Britney Spears continued to spend some quality time with her two sons during a trip to London Zoo yesterday.

The singer played doting mother as she enjoyed a family day out with Sean Preston, three, and Jayden James, two.

In between seeing the animals, Britney accompanied little Jayden on a carousel ride.

The adorable little boy tenderly rested his hand on his mother’s knee for comfort as they rode around in a mini red bus on the warm summer’s day.

Wearing a low-cut aquamarine vest and black jeans, the singer looked in her element.

Since arriving in London two weeks ago with her Circus Tour, Britney has been filling time away from the stage doting on her two boys.

She finished her stint at the O2 Arena in Greenwich on Sunday and has been enjoying a few days in the capital with her family before her gig in Manchester on Wednesday.

Their trip to the zoo comes a day after Britney treated her sons to a shopping spree at Hamleys.

The Thomas The Tank Engine fans explored the seven floors of toys as 27-year-old Britney helped them pick out some treats.

While in London, she is staying at the opulent Mandarin Oriental Hotel, which backs on to Kensington Gardens and Hyde Park.

Her sons are staying elsewhere, while her ex-husband Kevin Federline is also in London.

He agreed to come along on the tour so that the children were not separated from their mother for too long.

Britney  was even said to be paying him $4,000 a week to travel with her so she could be near them.

This week, lawyers for Spears and Federline reportedly filed documents with the U.S. family law Commissioner Scott Gordon, stating they have reached a new temporary custody arrangement.

U.S. gossip website TMZ reported that the family had agreed new custody arrangements for the tour.

Britney will have custody of her sons more than the 50 per cent of the time for the rest of June, July and August.

The tour is a family affair for Britney – who is also accompanied by her sister Jamie-Lynn and father Jamie, who is managing her affairs.

After her Manchester gig, she will head to Dublin for two more before going to France in July to continue her high-energy tour of Europe.
