US actor and new dad Ashton Kutcher has joined forces with Chinese tech company Lenovo to star in a new campaign for the brand's YOGA tablets.

Kutcher, who joined Lenovo as a product engineer last year, said 'The YOGA Tablet 2 Pro has got the best sound, a dramatically brilliant camera and display, a new mode, a projector and top processor, so I think we created the best tablet available. I can't wait for people to try it'.
