Rita Ora ran up a £10,000 bar bill in one evening.
The singer celebrated scoring her third consecutive number one single with 'Party (How We Do)' by having a big night out at London nightclub Mahiki.
The 21-year-old star was joined by friend Harley Alexander-Sule from Rizzle Kicks in the bar where they ordered champagne and £650 cocktails.
A source told the Daily Star newspaper: ''Rita was having a great time with her pal from Rizzle Kicks.
''She had the biggest table in the house and covered it with magnums of posh Ciroc Vodka.
''Rita also ordered a few of the infamous Mahiki Treasure Chest cocktails, which are £650 a go.
''Halfway through the night, management had to call for extra security to surround her table as she was getting a lot of attention from over-excited male fans.''
After leaving the club in the early hours of Tuesday morning (22.08.12), Rita and Harley shared a taxi home, after which she tweeted: ''Great bumpin into you at mahiki hope you got home safe @RizzleKicks !!!! (sic).''
Rita has said her sudden rise to fame has been overwhelming but she's planned her career for so long, she's dealing well with it.
She told the Daily Mirror newspaper: ''It feels amazing. I'm so chuffed. Stardom, it's a funny thing.
''You never know what it's like until you're in it. I knew what I had to do, what I had to sacrifice and it's not a problem. With the right team around you, you can control it.''
