Roswell star Shiri Appleby has revealed why she loved starring in new drama UnREAL.

Shiri plays TV producer Rachel in the new Lifetime show about what goes on off camera on a Bachelor-inspired reality TV show.

As her character works behind the scenes as a runner on the show, she was dressed down in jeans and a t-shirt with barely any make-up, while the actresses playing reality contestants had to pile it on.

Shiri says: “It was freeing. It took me 20 minutes to go through hair and make-up every day, that’s it, and it was the best thing ever.

“It was just really freeing. I loved it, I really did.”

But because the show is centred on a TV crew, the 36-year-old actress admitted it could get a little confusing, and people would mistake her for a real member of the crew.

Shiri explains: “It took us two or three episodes at least, to work out who really worked on the show and who was part of the cast.

“People would come up to me asking me for directions, or asking me what’s going on, thinking that I was actually a PA.”

UnREAL premieres on Lifetime on Tuesday 7 July at 10.00pm.
