Washington, Nov 13 : American R&B singer-songwriter Beyonce Knowles has denied leaking Justin Timberlake’s brand new track online.

The track is said to have been written for her by Timberlake.

Now, Timberlake’s representatives are puzzled as to how the recording of him performing the new track, Magic, found its way onto the Internet.

Though it has been alleged that the song was written for Knowles, her manager father Mathew Knowles has denied knowing anything about the controversy.

“(The track) was never presented to me personally. We have a good relationship with Justin,” Contactmusic quoted him as telling Us Weekly magazine. (ANI)
