As she left Cafe de Paris, the Sucker Punch premiere after-party venue, Vanessa Hudgens covered her hair with a pearl-coloured pashmina – and that isn’t the only thing she is keeping under wraps.

Vanessa is remaining tight-lipped about her relationship with her Journey 2 co-star Josh Hutcherson, who she has been spending increasing amounts of time with in recent months.

In fact as the actress took to the red carpet last night she refused to give anything away about her feelings for the 18-year-old actor-but she did let out a telling giggle.

Dressed in a flowing backless pearl floor-length gown by Alberta Ferretti, the actress had her hair in an elegant up style showing off her butterfly tattoo on her neck.

The actress may not have wanted to speak about her male co-stars but she did speak about working with Kristen Davies and said revealed that she would consider a role in a possible Sex and The City prequel film.
