Federline jets to London for Spears tour

Kevin Federline has arrived in London to support his ex-wife Britney Spears on the European leg of her current world tour.

The aspiring rapper and his volleyball player girlfriend Victoria Prince jetted into Britain this afternoon ahead of Spears's first performance in her eight-date residency at the capital's O2 arena.

He had previously agreed to join the 'Womanizer' star in Europe so that she could continue travelling with their two young sons, who accompanied her throughout her North American shows.

Federline has had custody of three-year-old Sean Preston and Jayden James, 2, since 2007 and was reportedly paid around $5,000 per week by his former wife to accompany the boys on the US leg.
