Natalie Portman says Chris Hemsworth would hide behind a tree to avoid drawing attention while picking up his kids from school

• Natalie Portman appeared on "Jimmy Kimmel Live!" and spoke about her "Thor" costar Chris Hemsworth.
• She said she "felt so bad" seeing him hide behind a tree to avoid attention at school pickup.

Natalie Portman said her "Thor: Love and Thunder" costar Chris Hemsworth's popularity made him stand out while picking up his kids from school.

During an appearance on ABC's "Jimmy Kimmel Live!" on Friday, Portman spoke with the guest host Sean Hayes about filming the fourth stand-alone "Thor" movie in Hemsworth's home country of Australia.

She said her husband, Benjamin Millepied, and their two kids, Aleph and Amalia, stayed with her in Australia while she filmed "Thor: Love and Thunder." Her children were also able to attend school in person, coincidentally at the same school as Hemsworth's kids.

Hemsworth shares three kids with his wife, Elsa Pataky — their daughter, India, and twin sons, Tristan and Sasha.

"It was really cool, and it was nice for them to have other kids who were new," Portman said.

Portman went on to describe an incident in which Hemsworth attracted the attention of other people while picking up his kids.

"One day, we ended up at school pickup at the same time, and I just felt so bad for him," she said, "because I'm small and can kind of camouflage with the moms. And then he comes in. He's like a Greek god walking through."

Portman added: "He's really famous everywhere but especially in Australia, he's so, so well-known. So to see him kind of by the tree, hiding, it felt like some weird sitcom of the superheroes at school pickup."

"Thor: Love and Thunder," starring Portman and Hemsworth, hits theaters on July 8.
