It's amazing what party tricks a gal has up her sleeve.
Or under her top, for that matter.
Just ask Kate Beckinsale. On becoming a mum, the Underworld: Evolution actress discovered a talent she never knew she had.
Whilst feeding her baby daughter Lily - from her previous relationship with actor Michael Sheen - she found she could squirt her breast milk across the room and "hit the wall from quite a distance".
We're not sure when this might come in handy, but it's impressive all the same.
Kate revealed her "useless talent" (the boob trick, of course) to US chat show host Jay Leno.
Kate, who's now married to film director Len Wiseman, also said she's ruled out any chance of starring in the new Wonder Woman movie for fear of embarrassing her daughter.
"I don't think appearing in my underpants is appropriate," she said.
Another brunette Brit is hotly-tipped to play the whip-wielding superhero - Catherine Zeta-Jones.
