Niall Horan has joked that he and the rest of the One Direction boys have been corrupting the mind of newly single man Liam Payne.

The 'One Thing' singer playfully told The Daily Star that since Liam's split from dancer Danielle Peazer, the 18-year-old has become a little "wild".

"We were talking about chucking TVs out of windows just the other day and I think Liam is up for it," Niall told the tabloid.

"He's going off the rails a bit to be honest, what with shaving his head and all that. Rehab is just round the corner."

Well Liam has certainly been going through some transformation, with the newly shaved head and everything, but Niall was obviously joking about the rehab part - we hope!
