Victoria Beckham never fails to surprise us. From her unexpectedly domestic baking skillz to the shockingly mushy speech she gave at the Glamour 2015 Women of the Year Awards, she’s a woman of many facets. The latest side she’s showing off? A humorous one.

Though she’s known for rarely cracking a grin, Victoria showed she has a sense of humor after all with this hilarious snap of herself with son Brooklyn. Wearing a mask meant to be his own mother, Brooklyn gives us his best Posh Spice, exaggerated lean and all. Victoria takes the joke in stride, writing “Great night hanging with Posh! Who knew she was so much fun?!?!…Love you @brooklynbeckham@davidbeckham.”

Ever the fashionista, V still found room to comment on her outfit, adding, “Wearing one of my new pre-collection pieces!” Of course she is: She’s still Victoria Beckham, after all!
