Actor and model Greg Plitt has passed away after being hit by a train in LA. The 37-year-old was killed yesterday afternoon when he was hit by a Metrolink train. Witnesses had seen him near the tracks with a video camera in his hand.

Pitt was a renowned personal trainer who had recently appeared in a reality show on Bravo called "Work Out", and is due to feature in a new reality series called "Friends to Lovers" later this month.

He had also acted in a number of Hollywood films, with roles alongside Robert DeNiro and Matt Damon in “The Good Shepherd” and he was cast in “Terminator 4” alongside Christian Bale.

He was also a body double in superhero movie Watchmen. Tributes have been flooding in for the fitness guru since the tragic news broke earlier today.
