Washington, Feb 24: Pop princess Britney Spears' one-time manager, Sam Lutfi, has denied that he threatened her with violence.

Spears' father, Jamie, had testified that Lutfi initiated direct communication with the Toxic singer and was harassing her, despite the temporary restraining order that he's under.

But Lutfi has denied all claims, and the restraining order against him has not been changed.

"Any communication Lutfi purportedly had with Britney were conveyed by and between Lutfi and Britney through others, including, without limitation, Mr. Ghalib," Us magazine quoted court papers filed by Lutfi''s attorneys as stating.

"I have not, in any alleged communications with Britney, her hairdresser or any other person, threatened any act of violence against Britney or her family," Lutfi added in a sworn declaration. (ANI)
