The 56-year-old actor and his 24-year-old rumored girlfriend posed with Elvis Mitchell during the Film Independent's evening dedicated to the actor at LACMA.
Penn, who has a 25-year-old daughter and a 23-year-old son, appeared to still be in vacation mode as he showed up in khaki shorts, matching high-top boots and a denim shirt. As for George, she wore a bright red wig and a black dress that had a sheer mesh on the shoulders and stomach areas.
The two returned to California after a recent trip to the coast of Oahu, Hawaii, where they were spotted making out and frolicking in the ocean together.
George, who made her acting debut alongside James Franco and Tori Spelling in the TV movie Mother, May I Sleep With Danger back in June, is the daughter of 57-year-old Law & Order: Criminal Intent star Vincent D'Onofrio and his ex-girlfriend, Greta Scacchi.
Aside from their recent red carpet appearance, Penn and George have not gone public with their relationship, but George did share an Instagram photo on Sept. 25 of her and Penn hanging out in a recording studio. "In the studio today recording the audiobook of Pappy Pariah's men-noir Bob Honey: Who Just Do Stuff," she captioned the vintage-style snapshot.
