One Direction New Music Video For 'Steal My Girl': You Won't Believe Who's In It!

One Direction fans are going to go crazy for the hints the group is dropping for the video to their new song "Steal My Girl," but it's the star of the video that has got everyone talking.

One Direction's Twitter was filled with photos of Hollywood legend Danny DeVito helping the boys, Harry Styles, Niall Horan, Zayn Malik, Louis Tomlinson and Liam Payne, with their new music video.

"So the #StealMyGirlVideo was filmed with @DannyDeVito !!!!!!!!!!" they tweeted.

Band member Niall couldn't believe it either, "Can't believe that Hollywood royalty Danny DeVito is in the 'Steal My Girl' video! What a legend!" he wrote.

The Batman Returns star was also having fun with the "Story of My Life" singers by posing with the group and his "Trollfoot." One even included Louis and a monkey!

1D fans may be too young to know who Danny DeVito is, but they should watch It's Always Sunny in Philadelphia, Matilda, and old episodes of Taxi to see the icon in action.

"Steal My Girl" is the first single from the mega-group's fourth album "Four." It's even co-written by Liam and Louis!

No word yet on what the video is about, but if it has monkeys and Danny DeVito then we can't wait!

How excited are you One Directioners to see the "Steal My Girl" video?!
