has proved that she can party just as hard as her American counterparts.
The R.I.P singer dropped a massive £10k on drinks in just three hours at celebrity hotspot Mahiki to celebrate her record-breaking third consecutive number one song How We Do (Party).
The 21-year-old has obviously been taking tips from her mentor Jay-Z
, who's known for his tendency to splash the cash on his nights out.
A source told The Sun: “Rita had the main table and was drinking Ciroc Vodka magnums and Treasure Chests. She spent about £10k treating her friends to a night to remember.
"When How We Do came on she headed onto the dance floor and went crazy."
The west London singer, originally from Kosovo, has been partying all week to celebrate her rapidly sky-rocketing career.
The excited star was all smiles when she eventually emerged from Mahiki at 2.30am, with her partner-in-crime Rizzle Kicks
star Harley 'Sylvester' Alexander-Sule at her side.
The pair looked remarkably fresh-faced considering the large bar tab and they were both seen clambering into a taxi with friends at the end of the night.
Rita even sweetly tweeted the boys to thank them for a good night: "Great bumpin into you at Mahiki hope you got home safe @RizzleKicks !!!!"
Nation singer is no doubt letting off some steam as she has a hectic few weeks of work ahead, which include her first headline tour.
As she was rolling into bed in the early hours of the morning Rita tweeted her fans: “Party + bullsh*t!! I love you. Goodnight. X”
