London: Actor Dominic Cooper, who previously dated fellow ‘Mamma Mia!’ star Amanda Seyfried, thinks actors date their co-stars because of the dynamic on-screen chemistry between them.

The 34-year-old has also been romantically linked to actresses Ruth Negga and Gemma Arterton and said they tend to spend a lot of time together while shooting for a film, reported a website.

"There are parts where for 12 hours on that day you are portraying someone who is so in love that they are on the cusp of insanity - so you can understand that dynamic chemistry," he said.

Cooper said he hates being the subject of public scrutiny because speculation about his personal life were really damaging.

"Fame is a difficult thing to be thrown into and I`ve been burned in the past. The rumour mill can be funny, but unfortunately it can also be really damaging."
