Audrina Patridge thinks social media would have destroyed 'The Hills'.

She admitted: "You can't have a real relationship on that show.

"'The Hills', any real relationship you'd bring on or try to have, it would get ruined. ...

"I think if social media was a thing, 'The Hills' would never be what it was. Even now going to dinner [fans] sit there and take pictures and film, and like, listen. The secrets! There would be no secrets at 'The Hills' anymore if there was social media back then!"

Audrina admitted she was really "upset" and became "distrustful" of show bosses when a storyline was staged for her to date Spencer Pratt, who is now married to co-star Heidi Montag.

She told Us Weekly magazine: "Oh God, no! I did not have history with him and this was one of the things that really upset me and this was when I started distrusting the producers."

Recalling when she was asked to go to a Pinkberry frozen yoghurt store with no explanation, only for Spencer, 32, to appear with flowers, she added: "That was all fabricated for drama because they needed something to film.

"And I think that was one of the first dramatic -- that's what started all the drama."

And her on/off romance with Justin Bobby - which grew more complicated when Kristin Cavallari joined the cast and began to date him eventually became "really weird" for Audrina because she was no longer interested in him and had begun romancing someone else off-screen.

She said: "Yeah, it was really weird for everyone and then it just wasn't genuine.

"It was really weird, and then whenever the producers kept wanting me to fight with her over him, I was like, 'I'm not doing that! I'm not even with him! I'm with someone else!' It really was hard with my real life and then my TV life."
