The actress, 35, appeared to be in good spirits as she laughed and smiled while leaving the private members' only venue in the early hours of the morning.

Keep it Chloé this summer in a dress like Sienna Miller's
Sienna Miller has always been a bit of a style icon and we've spent many an hour obsessing over her looks as well as plenty of money trying to recreate her most iconic ensembles.
And last night she pulled it out of the bag again. In fact she went to the middle of her no doubt extensive wardrobe to find this amazing midi by one of her go to labels, Chloé. It's from the brand's SS14 collection so it's practically vintage!
What's not to love about this très chic number? The thigh splits and plunging neckline bring the sex appeal; the handkerchief hem keeps it Boho just like all our favourite Sienna looks and the metallic print and the chain details give it edgy glamour.
Of course it has long been sold out but you can shop the current Chloé line at Net-a-Porter (right) or try our pick of dresses below. Asos provides the hardware detailing, T by Alexander Wang the print, while Caravana does an extreme plunging neckline and handkerchief hem.
The Hollywood star proved her fashion icon status by looking sensational in a pretty frock with plunging neckline, covered in delicate gold pattern details.
Falling to her ankles, the floaty material of the dress was perfect for a hot summer's night, while a thigh high split gave onlookers a cheeky glimpse at the starlet's shapely and tanned legs.
The delicate double gold spaghetti straps flaunted the English rose's toned arms and shoulders, and an assortment of gold chains built into the fabric of the frock added an interesting detail to the outfit.
The pretty star slipped on a pair of thick strapped black ankle sandals, and carried her essentials in an oversized black shoulder bag, embellished with white designs across the seams and straps.

She kept her trademark glossy blonde locks loose and styled them in tousled waves, while her makeup was au naturel, allowing the actress's dewy skin and natural beauty to shine through.
A simple gold watch was the final accessory needed to finish the look.
Sienna's night on the town comes amid romance rumours with Hollywood heartthrob Brad Pitt, 53.
The pair were linked after they were spotted flirting at Glastonbury Festival in Somerset, south-west England, in late June.
But friends of the actress have said she is still dating director Bennett Miller.

A source told MailOnline at the time: 'Sienna's finding it all very funny with friends texting her about being dubbed Brienna. She's happily with Bennett and has no idea where these rumours keep coming from.
'They're just not true. Brad's a great friend but nothing more. They were hanging out at the Rabbit Hole at Glastonbury but they were with a big group.'
Brad has six children with estranged wife Angelina Jolie, 42; Maddox, 15, Pax, 13, Zahara, 12, Shiloh, 11, and 8-year-old twins Knox and Vivienne.
Sienna's currently flexing her acting chops on stage at the Apollo Theatre starring in a revival of Tennessee Williams' play Cat on a Hot Tin Roof.
The play, co-starring actor Jack O'Connell, runs until October 7.

Sienna, mother to daughter Marlowe, four, with ex Tom Sturridge, has said she'd like to take time off and live in the country once production on Cat on a Hot Tin Roof finishes.
And in an interview with The Daily Telegraph in June, she said she lives each day as it comes and tries not to worry about future work or whether roles may became more sparse as she grows older.
'I don’t think about it, I’m quite good at being exactly in the moment where I am,' she said.
'I think the world’s changing, I have actress friends in their 50s who are really hitting their stride now – Robin Wright is in House of Cards and and is now having a spin-off. And the theatre is ageless.'
