If you don’t follow Kate Beckinsale on Instagram, you probably think of her as a serious actress. Most of her acting roles have been in either period dramas or action films, and she plays a fierce vampire warrior in her latest movie, Underworld: Blood Wars. Last month, we wrote about the brutal workouts that earned Beckinsale a place on the cover of Shape. Meanwhile, her Instagram captions offer a peek at the personality beneath that stunning surface. It turns out, she’s both silly and self-deprecating.

Her latest post, a mirror selfie she apparently took during her Shape photo shoot is captioned “Laughing in bathrooms with friends.”

Yesterday, she posted a close-up shot with the caption, “You can think you’ve had a reasonably good day until you get undressed at night and two small pieces of chicken fall out of your polo neck.”

Saturday, a British graphic designer posted a photo of his bunny next to its litter box, which was lined with a newspaper with Beckinsale’s photo. She reposted the pic on her own account with the caption, “Happy to be of service.”

Two weeks ago, she shared another photo from the Shape shoot, where she strikes a dramatic pose in a strapless bikini top. The caption reads, “It’s Monday morning. Sniff your armpit and then try to twist your own head off who’s with me.” For more of Kate’s funny captions, (and the hotness that accompanies them) follow her yourself.
