Joseph Shabani, the man who supposedly tried to ram David Beckham off the road after claiming the soccer superstar had a fling with his wife, is speaking out for the first time and declaring: "I believe she had an affair."

EXCLUSIVE COURT DOCUMENTS: Read the Declaration

Shery Shabani, a Beverly Hills mother-of-two claimed Joseph, also known as Kambiz, tried to run Becks off the road outside their children's school after wrongly accusing the pair of having an illicit tryst.

In a declaration to a Los Angeles court, in response to his soon-to-be ex-wife explosive charge, Joseph wrote: "Petitioner (Shery) and I have been experiencing marital troubles for many months, due to my belief that Petitioner (Shery) has had an affair."

He did not name Beckham in the court filing.
