The 28-year-old actress took to her Instagram account in the early hours of Saturday morning (31.01.15) to share a funny snap of herself, the 'Hunger Games' star, and a small group of girl pals at an alcohol-fuelled birthday bash for mutual friend Lauren Ash.

In the photograph, Rebel is seen grinning at the camera, the other girls smiled and stuck their tongues out, while Jennifer, 24, flipped the bird with a cheeky open-mouthed expression on her face.

The 'Pitch Perfect' star accompanied the grainy snap with the sarcastic caption: "Nobody was drunk at @lauren_ash 's birthday tonight..."

Meanwhile, that wasn't the only girly night out Jennifer - who is currently dating Coldplay frontman Chris Martin - enjoyed last week as she was also spotted tucking in to a delicious meal with Adele, 36, at the exclusive Craig's restaurant in West Hollywood, California, on Thursday (29.01.15).

An onlooker told JustJared: "Adele and Jen were both in very good spirits the whole night.

"They were both wearing heels and dressed in head-to-toe black. Jen wore her hair down in a straight bob and looked super cute!"

Rebel, on the other hand, also had a busy weekend as she attended the 2015 G'Day USA gala on Sunday (01.02.15) and rubbed shoulders with fellow Australian stars, brothers Liam and Chris Hemsworth, Nicole Kidman and Russell Crowe.
