(Cover) - EN Showbiz - Emily Browning has revealed that her Sucker Punch co-star Jena Malone is a karaoke addict.

Emily and Jena appear together alongside fellow actresses Abbie Cornish, Vanessa Hudgens and Jamie Chung in the upcoming thriller about a young girl who is institutionalised by her evil stepfather and comes up with a plan to escape.

The girls have been vocal about how well they all got along on set, although Emily has admitted she didnt appreciate one of Jenas favourite pastimes.

I personally am not particularly fond of karaoke but Jena Malone has a bit of a karaoke addiction and she sort of forces us to do karaoke every now and again, the actress told Collider.

I remember Jen and I did 4 Non Blondes, it was abysmal... oh so bad. I mean Jen was great cos she just sort of ad-libbed but I was like, Ooh I cant do this.

Emily was discussing the cringe-worthy incident in a joint interview with her co-star Abbie, who admitted she isnt fond of singing either. The actress does have another musical talent though, and considers herself to be quite the hip-hop star.

Well, Im not a singer but I rap so I have a tendency to burst into freestyle rapping and beat boxing, she explained.

Emily appreciates Abbies rhyming skills, which she describes as extremely entertaining. The star believes all of the Sucker Punch cast got along so well because they had no time to worry about being self-conscious and had to get into the movies gritty action scenes straight away.

We had no guard up, there was nothing superficial going on. We were just in there sweating and bleeding and crying together automatically like the first day that we met and I think that just forms an instant bond, added Emily. (C) Cover Media
