Bruno Mars' London album launch proved such a big hit on Monday (24Jan11), more than 300 people were turned away from the R&B star's afterparty.
The Just The Way You Are hitmaker performed a special gig at the U.K. capital's Cafe De Paris to mark his debut record Doo-Wops & Hooligans topping Britain's album chart on Sunday (23Jan11).
He later moved on to West End club Merah to continue his celebrations - but the venue filled up so quickly, hundreds of eager fans were denied entry, according to Britain's The Sun.
The publication also reports Mars racked up an $18,000 (£12,000) bar bill at the hotspot.
