Her hush hush wedding was done in under a cloak of secrecy with just four guests in attendance. So naturally Cheryl Fernandez-Versini was in the mood to celebrate her new marital status when she was back with friends and family in London.
The Crazy Stupid Love singer and her new man looked the image of newly-wedded bliss as they arrived at The Library club in St Martin's Lane.

Cheryl was chic in a midnight black gown featuring a sheer pleated French chiffon skirt by Ralph & Russo. And giving her all-black outfit extra special sparkle was her beautiful diamond engagement ring and wedding band.
Jean-Bernard colour coordinated with his new wife, stepping out in a dapper black suit.

The new Mr and Mrs Fernandez-Versini were joined by a number of high profile names at their party, which seemed to have a colour theme of monochrome.
Cheryl's Girls Aloud bandmates Kimberley Walsh and Nicola Roberts attended, and Cheryl was excited to be joined by the ladies on her special night.
She tweeted: "@NicolaRoberts @KimberleyJWalsh @FrankieRoberts8 I love you more than you can imagine !!"
Former bandmate Nicola Roberts was in attendance
Nicola looked stylish in a black-and-white mermaid gown with button detail while Kimberley – who was escorted by her partner Justin Scott - showed off her cute baby bump in a black jumpsuit.
Other guests included Rochelle and Marvin Humes, and joining the celebrity contingint was Cheryl's mum Joan Callaghan.

Joan was one of the four guests present when Cheryl and Jean-Bernard said "I do" during a romantic beach ceremony on the island of Mustique.
The others were the Geordie beauty's brother Gary, her PA Lily England and Jean-Bernard's best friend Benjamin Bran.
Bishop Devom Ollivierre, who officiated, told newspapers: "They seemed very in love. The atmosphere was incredibly captivating."
One of her closest friends told HELLO! magazine: "Cheryl is incredibly happy, she genuinely is crazy in love with JB."
