Kate Beckinsale [1] may be a well-known actress, but she's also an embarrassing mom. During an appearance on The Late Late Show With James Corden on Tuesday night, the Love & Friendship star told the host about how she celebrated her daughter Lily's 16th birthday last year by hilariously re-creating her birth with her ex-partner, Michael Sheen. Kate, who was with the actor from 1996 until 2003, also shared a side-by-side photo of the moment on Instagram writing, "Always a baby to me #Lily -- See more tonight on the @latelateshow ✨" Not only is the snap the ultimate throwback pic, but it also proves that Kate hasn't aged a bit!
