Jack Nicholson and Meryl Streep had fling while filming 'Ironweed'

Jack Nicholson and Meryl Streep had a fling while shooting for 'Ironweed' in 1987, it has been revealed.

According to Mark Eliot's new biography 'Nicholson', the now 76-year-old actor had allegedly struck up a relationship with the actress and even claimed the pair had sex in his trailer on set, the mirror reported.

The book states that as soon as the filming of 'Ironweed' began, rumours exploded that the pair had grown unusually close, as everyone on set and those who heard bout it, were not talking about the film's script, or direction, or scenic design, but about Nicholson and Streep.

However, both had denied it then as it was in a bit of a bind that Nicholson was actively, if secretly, still seeing Cartwright.

The pair had first met in 1985 when they starred together in 'Heartburn', but filming had ended with Streep throwing him out of her hotel room and claiming that she would never work with him again because of his "relentless sexual overtures".
