Natalie Portman pregnant with Baby No. 2, debuts baby bump in most glamorous way possible

Natalie Portman will soon have another tiny dancer at home!

The Oscar winner, 35, put her burgeoning bump on display in a striking white Dior gown at the premiere of her new film, Planetarium, at the Venice Film Festival on September 8.

And yes, multiple multiple have confirmed that she is in fact pregnant and did not just eat a very large sandwich before the event.

Already mum to 5-year-old son Alephi, this will be the actress' second child with her French ballet director husband – who she met on the set of 2010's Black Swan – Benjamin Millipied, 39.

Natalie was joined on the red carpet by her Planetarium co-star Lily Rose-Depp (Yep, Johnny Depp's 17-year-old daughter), who plays Natalie's younger sister and fellow psychic in the indie film.

"I love being a mum," Natalie told Elle UK in 2013. "But it’s much more intensive work than being an actress – going to work feels like you’ve got a day off.

"Not that I want a day off from being a mum, it’s just perhaps I had this impression before that mums don’t work. But they work more than anyone."
