Britney on Kevin's case about his partying

Britney Spears and Kevin Federline had a massive bust-up at the US premiere of 'Charlie and the Chocolate Factory', it has been claimed. The pregnant singer, who is rumoured to be expecting twins, and Kevin arrived at the Hollywood premiere of the children's film, starring Johnny Depp, smiling and looking happy. However, Britney - who wore a blue vest with words "I have the golden ticket" accompanied with an arrow pointing to her swollen bump - was later seen blasting Kevin at the premiere party over his excessive drinking and smoking. According to reports, the 23-year-old was furious with her husband and began lambasting him for smoking around her while she is still pregnant. A source said: "Britney told Kevin to avoid the free booze at the party and top lay off the cigarettes. She's sick of all the speculation surrounding his decision to keep smoking while she's pregnant.
