You may remember Lewis, 35, as a rich girl scout in Troop Beverly Hills, as Fred Savage's young love interest in The Wizard, as part of Angelina Jolie's circle of gal pals in Foxfire, or as Gyllenhaal's girlfriend back in 2001.
The former child actress, who has become a singing indie rock favorite by fronting band Rilo Kiley and releasing two solo albums, has remained friends with the Globe nominee, even after moving on and dating other people.
Back in 2009, Gyllenhaal, 30, caught Lewis's set at the Coachella Valley Music & Arts Festival with then girlfriend Reese Witherspoon. Later that year Lewis, who is currently dating fellow musician Johnathan Rice, hung out with the couple after her concert at the Hollywood Bowl. And Gyllenhaal wore a sweatshirt with Lewis's face on it while exiting a gym in Studio City last June.
Sunday night, they were back to supporting one another with Lewis on Gyllenhaal's arm at the Golden Globes. With his short-lived romance with Taylor Swift on everyone's mind, who says ex's can't be friends?
