Kate Beckinsale is at the top of her Instagram game. We told you last week that the actress clued us in on her top three picks for the best smelling celebrities, and the unusual and riveting posts just keep on coming.

Yesterday, Kate shared a picture of her mom “mooning” the camera with a plastic butt mold where her own would be. For a moment, it looks real, and it did make us laugh! The caption reads, “When it’s raining or I’m having one of those days I remember that my mother knows how to have fun with a false are and I instantly cheer up,” with the hashtags “#mondaymotivation, #legend #buffalostance.” Check it out:
