Natalie Portman sparked pregnancy rumors at the Venice Film Festival on Wednesday while in town to promote her new film Jackie.
Wearing a loose-fitting, embellished dress, the actress appeared to be sporting a tiny baby bump, though she has yet to address reports.
If the Oscar winner is expecting, this would be her second child with husband Benjamin Millepied, whom she married in 2012. They welcomed a son named Aleph in June 2011.
The 35-year-old has largely been out of the spotlight since giving birth, except to reprise her role as Jane Foster in Thor: The Dark World.
In her latest project, she portrays former first lady Jacqueline Kennedy in the aftermath of her husband JFK's assassination.
