Aguilera's small tip

Pop babe Christina Aguilera reportedly stormed out of a restaurant after staff challenged her meagre $12 (€9.80) tip.

The Dirrty star sat down for a $400 (€326.10) meal with pals at an exclusive Miami, Florida, hotel, but when waiters informed her gratuity failed to cover the 15 per cent service charge, she walked out in a rage.
