Thought that Britney Spears’ 16-year-old sister getting knocked up was as bad as it got for the family? Not even close – Britney Spears now apparently thinks her two baby sons have been taking drugs.

Well, sort of – Britney Spears has decided to turn on the attack in her child custody battle with Kevin Federline by apparently claiming that he smokes pot in front of Sean Preston and Jayden James, and that as a result they’re breathing in all his second-hand drug-smoke. It’s thought that Britney Spears was alerted to this possibility by the way that her kids sitting around staring into space and giggling all day. However this might not mean that the Federline-Spears kids are stoned – it might just mean that they’re either a) children or b) genetically very stupid. Really, the truth is that it could be any of these things.
