Whenever Lena Headey, the star of 300: Rise of an Empire (out March 7) needs a laugh, she looks at her California driver's license. "The photo was taken just before I had my son, so I was 60 pounds heavier and my hair was white-blonde," the 40-year-old Game of Thrones actress, mom of Wylie, 3, tells Us Weekly. "I look like Brigitte Nielsen on steroids!" Also in her Foley + Corinna purse?

New Addiction 

"I carry about eight lip balms: Burt's Bee's, Rosebud Salve, Eos. It's because I quit smoking in October and I still have an oral fixation." 

Spare Skivvies 

"I keep an extra pair of my son's underwear on me. You never know what's going to happen! So I have a tiny man's Y-fronts in my bag, which may be weird." 

Hard to Swallow

"I usually bring along a bottle of kombucha, thinking, This will be really good for me. But I never actually drink it. The fermented mushroom-y flavor is too intense for me. It's almost like taking a big slug of alcohol." 

That's a Wrap

"I always have scarves handy; they're my indulgence. I buy them at an L.A. shop called Lost & Found. I'll spray one with loads of my Byredo Gypsy Water perfume, put it on and be like, Ah, this feels good." 

Boy Toys

"Often I have a random Ninja Turtle or a Power Ranger with me. It's so glamorous, my bag, isn't it?"
