It's all relative: Cameron Diaz and Nicole Richie enjoy a double date night as they support partners Benji and Joel Madden at Good Charlotte gig 

They've become increasingly close since they became sisters-in-law in January.

And Cameron Diaz and Nicole Richie relished their supporting-wife roles as they enjoyed a double date with their husbands and twin brothers Benji and Joel Madden, respectively, on Thursday evening.

The Sex Tape actress and the Candidly Nicole star stood by their spouses as they attended their Good Charlotte gig at the Troubadour in West Hollywood, California.

Cameron, 43, and Nicole, 34, were both suitably styled for the occasion with Cameron favouring a more casual look to Nicole.

The Golden Globe nominee slipped on a camo-printed shirt which she wore buttoned up and teamed with a pair of slightly-distressed blue jeans.

She carried her possessions in a studded mini across-the-body handbag while a strong red lip and matching nail polish ensured she looked every inch the rocker's wife.

Cameron was pictured leaving the venue hand-in-hand with Benji, 36, as she led the way from the back door to their getaway car.

Meanwhile, mother-of-two Nicole was equally keen to make a sharp exit and she was seen clinging onto the arm of Joel as they headed home.

She cut a characteristically classic figure dressed in an all-black ensemble which comprised tailored jumpsuit and suede court heels.

The former Simple Life star tucked her silver-dyed bob behind her ears and was lightly made-up.

While Nicole and Joel headed home together, Cameron and Benji clambered into a chauffeur-driven vehicle with fellow gig-goer and British pop export Jessie J,

The guitarist was pictured sitting next to Jessie, 27, while his wife sat behind him.

Cameron and Benji married in her Beverly Hills home on January 5 after a whirlwind 17-day engagement, having been introduced by Nicole seven months earlier.

Meanwhile, Nicole and Joel became man and wife in December 2010.

They have two children - daughter Harlow and son Sparrow - together.
