The couple may be planning a unique honeymoon

Mila Kunis and Ashton Kutcher are reportedly planning to get hitched in France this autumn – and could be jetting off on a very unusual honeymoon.

Ashton, 35, wants to whisk Mila, 29 – who he’s been dating for over a year – off to space in Richard Branson‘s £124,000-per-seat SpaceShipTwo.

‘They decided together they want their big day in September, probably on one of St Tropez’s beaches,’ a source tells The Sun.

Ashton is already going into space on Branson‘s Virgin Galactic flight and he has said Mila will definitely be at his side as his honeymoon present.’

Mila and Ashton recently holidayed in St Tropez with new friends Princess Beatrice and her boyfriend Dave Clark, who’s head of astronaut relations at Virgin Galactic.

More than 600 people have signed up for the trip, with stars including Justin Bieber and Russell Brand believed to be going on board.

While Mila hasn’t spoken about her rumoured nuptials, she recently revealed that being in a relationship is ‘great’.

‘You can ask me anything about Ashton; I won’t answer… but I can tell you love is great, love is wonderful and it’s all around us,’ Mila told Io Donna magazine.

‘See? I just gave you an awesome quote!’
