What is Farah doing in London with Akshay, Riteish, Bobby?

London calling for Bollywood!

Farah Khan took some time off her London holiday to choreograph a song for Housefull 4.

The fourth installment of the hit movie franchise will see new actors -- Bobby Deol, Kriti Sanon, Pooja Hegde and Kriti Kharbanda -- get together with the original cast of Akshay Kumar and Riteish Deshmukh. Sajid Khan returns to direct the film.

Catch the action from the sets.

'Its ok to work during ur holidays whn its with these 3.. @riteishd @akshaykumar @iambobbydeol,' Farah captions this picture on Instagram.

Farah writes, 'With the lovely ladies of #housefull4.. they really do get along.. coz heroines fighting is sooooo passe. @kritisanon @hegdepooja @kriti.kharbanda.'

She takes a picture with the film's producer Sajid Nadiadwala and writes, 'Brother in Arms! Shooting with #sajidnadiadwala is always Fun.. this time multiplied by 4!'

It's not all work and no play for the Housefull cast. Riteish posts a picture of Akshay, Bobby and himself sightseeing at London's Tower Bridge.
