British boxer Amir Khan has reportedly landed in hot water with his fiancee Faryal Makhdoom, who is believed to be eager to meet an ex-lover of the boxer to discover if he has been unfaithful.

The New York-based student is thought to have contacted glamour model Natalie Fox, who is said to have had a fling with Khan before he met Makhdoom, to find out whether the Bolton-born fighter had been seeing the model during their relationship, according to The Mirror.

Fox, who is believed to have met the boxer through mutual friends, has reportedly claimed that she slept with Khan two weeks before he announced his engagement to Makhdoom.

It is thought that 20-year-old Makhdoom is willing to meet Fox in person.
