Washington, January 16: Actress/singer Jennifer Lopez has cancelled her contract with her manager Irving Azoff, after an association of about one year.

The reason for their dissociation is yet unclear.

A representative for Lopez says that "she let him (Azoff) go on Friday with no drama", reports Contactmusic.

However, a tmz. com report suggests that Azoff has sacked Lopez for being "unprofessional", and for letting her husband Marc Anthony "constantly meddle" with her career.

Sources have revealed that Azoff sent Lopez a letter last week, mentioning what drove him to fire the singer.

This was reportedly followed by a "heated phone call" between Lopez's representatives and Azoff.

Azoff is well-known for the successes of supergroups the Eagles and Van Halen and British singer Seal. (ANI)
