She's not exactly renowned for being a wallflower when it comes to choosing outfits to wear.

But last night (Sunday) Lady Gaga took things to a whole other level as she partied in London with pals Rihanna and Jay-Z at the Arts Club in Mayfair.

The 26-year-old singer sported a very revealing white wedding gown as she arrived at the venue to begin her evening.

Gaga teamed the dress, which featured a corseted top which struggled to contain her ample cleavage, with a net turban-style headpiece, satin gloves and sky-high cream heels.

The Born This Way singer entered the nightspot in typically outrageous style, even enlisting a male helper to give her a hand with the voluminous gown.

But if Gaga's entrance was eye-catching, her exit was even more so, with the singer spreading her arms wide to give her the look of a white swan as she left the club via the fire exit.

The singer appeared slightly worse for wear as she called it a night following an eventful evening, and was photographed looking bleary-eyed as she headed back to her hotel.

However, the fun didn't stop for Gaga when she arrived back at her hotel, as she decided to sit on the steps of her temporary abode with a male fan who was dressed as John Lennon.

Blowing kisses at her fans, Gaga clutched a sign the fan had made which featured the slogan 'We Love London' as she was photographed ahead of going back up to her room.

Gaga's night out came after a spellbinding performance of her Born This Way Ball at Twickenham Stadium on Saturday night.

In her first live performance in the UK since December 2010, Gaga belted out her most famous tracks to a crowd of around 55,000 people.

The singer also unveiled a new track in tribute to the late Princess Diana, called Princess D.I.E.

'I swore if I ever had an audience like this in London I would take a moment to appreciate her.

'This song is called Princess Di - D-I-E... I predict controversy, but I don't care... Let's take a moment to appreciate her presence and what she means.'

This weekend also saw RIhanna unveil her new tattoo - a less than understated design on her ribcage which she had inked in tribute to her late grandmother Dolly.

Explaining the etching, which features the goddess Isis with her wings spread wide, Rihanna tweeted alongside a picture of the new addition to her collection: 'Complete Woman - Model for future generations- #GRANGRANDOLLY - always in and on my heart #1lo.'

But last night Rihanna opted to instead keep the design hidden beneath her modest T-shirt.
