TORONTO – Eminem mostly keeps his clothes on, but “8 Mile” boasts a steamy sex scene that had tongues wagging at its first public showing here.

His character, Rabbit, and his girlfriend, played by Brittany Murphy, do the nasty – in graphic ways that push the movie’s probable R rating to the limit – while standing up in the metal-pressing plant where Rabbit works.

In two other scenes, Rabbit surprises couples by walking in on them during the act – and one of the lusty participants is his mother, played by Kim Basinger.

Eminem does drop his own drawers at one point – to moon the audience during a rap competition.
