She hasn’t released an album for 4 years but the dosh keeps arriving

Britney Spears might not have been doing much in the last 4 years, but she’s still been raking in the money.

The troubled singer, 25, earns £4.5m a year, according to documents filed in her custody battle.

Kevin Federline’s lawyer Mark Vincent Kaplan claims Brit gets in an average of $737,868 (£366,204) per month – which is £4.5m a year.

And it turns out K-Fed, 29, collects £10,000 a month in spousal support, which is due to end on 15 November, reports the Daily Mail.

Kevin’s lawyers have argued that Britney should pay her ex-hubby £37,000 for his legal expenses.
