Actress Rose Byrne was left terrified after a massive spider appeared in a car she was driving in Australia.

The Bridesmaids star was vacationing in her native country in February (13), when she found a fearsome-looking Huntsman in the vehicle with her.

She says, "I was driving along and just where the sun visor is a spider dropped right down, a huntsman, and it spread out its legs right in front of me and I think it looked at me. I'm pretty sure it looked at me. I just went, (screams), and ran off to the side of the road and got out of the car and brushed myself off madly.

"I was like, 'OK, alright, great great, great,' got back into the car, drove along. Then it came up again onto the dashboard and I'm a bit scared of spiders, so I was totally, totally panicked. So I was like, (screams again), pulled over, rolled down the windows and went for like an hour walk to make sure the spider got out of the car."
