One Direction heartthrob Liam Payne has joked that he is a little concerned about the power his security team truly has because one of his body guards has been walking around singing Beyoncé songs. 

Writing on his official Twitter page this afternoon (April 8), the 'Story Of My Life' superstar explained that his 'tough guy' security guard doesn't seem so tough when he's singing along to her hit sings: "Those days when your tough guy body guard is singing Beyoncé... Just how safe am I #ToughGuysSingBeyonceToo."

Over the weekend, Payne told his followers that he's really excited to get back into the studio with Pharrell Williams and tweeted a message to the 'Happy' sensation, which read: "Happy birthday @Pharrell hope you have a great day look forward to getting back in the studio with you next time I'm in Cali."

The boyband, meanwhile, are currently gearing up to kick off their Where We Are tour, and have been rehearsing for the extensive run of dates. Member Harry Styles confessed to his fans on the social networking site that it's all very exciting:

"Rehearsals are going good for the tour, it's so soon. Can't wait to see you all."
