She's a talented actress and mammy to a three-year-old daughter and 10-month-old son.

That and Mila Kunis is also something of a mega-ride.

Now, a scour of Instagram has confirmed, the 34-year-old has swapped her trademark brunette tresses for a blonde bob. She looks incredible because she's Mila Kunis and we doubt she's ever looked anything but incredible, but the look is certainly stark and waaaaay different to what we're used to seeing her rock.

Mila was on the set of her new comedy, The Spy Who Dumped Me, and was filming Berlin... which makes us wonder whether she's actually reached for a bottle of bleach - or whether she's simply sporting a rather convincing wig.

Wigs have become seriously popular in recent times with celebrity-types - probably because they've become a lot more realistic and also because constantly dyeing and styling your hair takes its toll on your strands. For example, the Kardashian-Jenners (who else!), Blac Chyna, Nicki Minaj, and Rihanna are all big fans of a certain Toyko Stylez - who sources wigs for famous folk all the time.

Meanwhile, Mila has been married to Ashton Kutcher for two years, and together for five-and-a-half. They met on the set of The 70s Show in the late Nineties but they didn't become a couple until 2012.
