Liberty Ross stepped out on Wednesday night to attend the Los Angeles premiere of Lawless starring Shia LaBeouf.
Dressed in a silky green top, black leggings and ankle boots, the former model glowed as she posed for photos on the red carpet.
"Liberty was in a great mood," a source tells PEOPLE. "She was there to support her friend, [screenwriter] Nick Cave."
Following the screening, Ross attended the afterparty at Eden nightclub presented by DeLeón tequila, where she stayed until about 11:30 PM, having a great time.
Upon leaving the party, Ross was mobbed by paparazzi, eager to get a shot of her enjoying a night out following her husband Rupert Sanders's recent cheating scandal with Kristen Stewart.
