Kristen Stewart also enjoyed a long-term relationship with her 'Twilight' co-star Robert Pattinson.

The pair dated for five years until 2012 but looking back on it more recently, the 26-year-old actress feels it wasn't real life but more a "product".

She said: "People wanted me and Rob to be together so badly that our relationship was made into a product. It wasn't real life anymore. And that was gross to me.

"It's not that I want to hide who I am or hide anything I'm doing in my life. It's that I don't want to become a part of a story for entertainment value."

The pair's romance hit the rocks when she cheated on him with married 'Snow White And The Huntsman' director Rupert Sanders in 2012.

Robert is now happily engaged to singer FKA twigs, although the pair have had to push back their wedding to fit in with the actor's busy schedule.
