One Direction welcome a new band member!

Five hot singers isn't enough for One Direction it seems, as the group have taken on a new band member.

Well, kind of! 

Actor Danny DeVito is set to star in the lads' new music video for Steal My Girl, and he was definitely looking the part on set! Niall tweeted this picture with the excited message, "Cant believe that Hollywood Royalty @DannyDevito is in the steal my girl video! what a legend!"

The boys just look in awe of him – very cute!

Danny himself seemed delighted to be on set with Harry, Niall and co, sharing a couple of snaps of his own on social media:

The Matilda actor even got 1D involved in his famous Trollfoot "project", a set of photos all featuring his oh-so-pretty right foot:


Steal My Girl is the lead single from the lads' hotly anticipated album Four, which will be released on November 17th. We can't wait!
