The actor couple have chosen an apartment in Hampstead- a plush part of North London.
And the two lovebirds needn’t worry that they might get bored away from the Hollywood scene, as their home overlooks a car park in the heath notorious for ‘dogging’.
A rumoured favourite spot for stars including George Michael, the steamy area is said to come alive at night with frisky strangers.
Ashton Kutcher, 35, is joining girlfriend of one year Mila, 29, in London while she films her latest flick, Jupiter Ascending.
Speaking about the American couple’s choice of area, a source told a UK newspaper:
'Mila has come over to London ahead of Ashton to start shooting.'
'Ashton has a bit of time between projects so has decided to relocate to London and house-sit while Mila is at work.
They originally planned to move more central to Marylebone but she fell in love with Hampstead when she had a day off there with some friends.
The apartment they have is opposite a notorious car park on the heath which is well documented on the internet as a site for voyeurs seeking thrills with strangers.'
Ashton Kutcher will be relieved to be out of an awkward situation, as he has been staying in the same Covent Garden hotel as Mila’s ex of eight years, Home Alone star Macaulay Culkin.
The Butterfly Effect star is still technically married to Demi Moore, 50, though she has recently been linked to comedian Russell Brand, who used to own a house near Mila’s new home.
Phew, our poor little brains!
