Aussie Jesse Spencer, 34, heats things up on the May 15 season finale of the NBC series Chicago Fire and chatted with PEOPLE this week about "one last thing" ...

Last Sunburn

I'm really good at not getting sunburned because I wear zinc cream. On vacation in Indonesia, I ran out of skin-colored zinc, so I used green and locals called me Hulk.

Last Splurge

I bought a '68 Camaro last year. My first car was a '69 Holden, which is an Aussie car. I've been looking for a muscle car for ages. [I call it] the silver bullet. It's beautiful.

Last Romantic Gesture

I bought my girlfriend [Brazilian surfer Maya Gabeira, 26] two presents today. She was in Brazil for her birthday, so I'll have something for her when she comes back.

Last Thing I Cooked

I cooked myself scrambled eggs. I work 14-hour days on-set, and when you go home to an empty apartment, the last thing you're going to do is cook a meal. I eat cereal, eggs or smoothies. That's my routine.
