Kate Beckinsale is undoubtedly one of the hottest actresses around. And today, we're going to honor her in GIF form.

This 40-year-old hottie is like a fine wine and seems to get better with age. You probably know her best as the vampire Selene from the 'Underworld' film series, a character who made us wish she'd sink her fangs into our necks. You might also recognize her as the incredibly sexy MILF from the Adam Sandler comedy, 'Click.' We're supremely jealous of Sandler for getting to film a bedroom scene with her, even if it did last like.. five seconds.

Peep the GIFs below to see her in motion, writing around in various states of undress. Our imaginations are running wild thanks to this British vixen and we wouldn't have it any other way.
