Boozy Rihanna sparked fresh fears over her party lifestyle after clashing with bouncers in a nightclub. Rihanna, 24, was allowed to stay at the trendy London nightspot only after pals spoke out on her behalf — but left at 4am for ANOTHER party. Earlier the raging Bajan had screamed: “Don’t you know who I am?” as doormen grabbed her following her drunken fall. Bouncers moved in after the beauty, wearing thigh-high snakeskin boots, jumped on the private table, which broke apart and sent her crashing to the floor. Bottles of champagne and glasses shattered as she fell, drawing gasps from onlookers. Security hauled the singer away from the table in front of 300 revellers and a scuffle kicked off. Rihanna — seen downing champagne and cocktails — yelled at the bouncers while friends shouted at them to leave her alone. Rihanna, in the UK to work on her fashion collection, has been seen out and about regularly in the capital in the past week. Last May she admitted missing a flight because she was drunk. She was earlier seen necking drinks in a club. She woke up so tipsy at a hotel that she failed to catch her plane home to LA because she wanted to stay in bed. The star tweeted: “U know life is great when u wake up at 9am DRUNK!!!!!” Last night her spokesman said: “There’s no comment regarding this.”
