Long time fans of Grey’s Anatomy were devastated when Patrick Dempsey’s classic character, Dr Derek “McDreamy” Shepherd, was killed off recently.

The character’s death came as a shock – but there may be a reason behind Dempsey’s sudden departure.

New speculations claim that the 49-year-old actor was sacked from the long-running show because he was having an “inappropriate relationship” with an intern on set.

Rumour has it that co-star Ellen Pompeo found out about the affair and told Dempsey’s wife, Jillian Fink, which led to their split last January.

Of course, Dempsey has fiercely denied the rumours, with his representatives calling them “ridiculous”.

In Touch magazine, which broke the rumours, has since deleted the article from its website.
