Reports surfaced suggesting the "Saturday Night Live" regular was romancing Andie MacDowell's 24-year-old daughter earlier this week (begin August 26), and insiders hinted the couple would make its red carpet debut at the Venice Film Festival.
The stars didn't arrive together, but Pete was spotted sitting just behind the actress throughout the screening of the movie.
Davidson has nothing to promote at the festival.
The "Once Upon a Time in Hollywood" star previously dated actor Nat Wolff and new James Bond director Cary Fukunaga, while Davidson became tabloid fodder last year when he proposed to Ariana Grande following a whirlwind courtship. He also dated Kate Beckinsale earlier this year.
