Rita Ora turned heads as she arrived at London’s hotspot for her birthday bash. The RIP hit singer inadvertently flashed her knickers as she made her way to The Box, Tuesday, Nov. 26.

Following the retro-themed, star-studded party for her 23rd birthday celebration, Rita arrived at the nightclub in Central London, in a revealing red gown, with thigh-high slash.

Her security failed to hide the singer from intrusive shutterbugs as she was getting off the car and she accidentally flashed her knickers to onlookers and waiting paparazzis.

Looking very retro for the occasion, thanks to her stylist and friend, Kyle De’Volle, Rita’s 70s look was completed with a bouffant hair, initially hidden under the hood hanging loosely to cover her locks.

The red gown came in with plunging neckline that gave the shutterbugs a glimpse of her ample cleavage. It also revealed her toned legs as he was making her way inside the club.

The soiree was attended by friends and celebrities including Kelly Brook, rapper Eve, and Sarah Jane Crawford. And her birthday party would not have been complete without the presence of her boyfriend, Calvin Harris.

Rita and Calvin stayed up until wee hours in the morning and the birthday girl was seen leaving with beau, Calvin at 4:30 in the morning.

Other celebrities who attended Rita’s birthday bash included, Jaime Winstone and “Rizzle Kicks” star, Jordan Stephens.
