Drew Barrymore's sexy mystery

Drew Barrymore thinks mystery is "sexy".

The actress - who has refused to confirm reports she has rekindled her romance with Justin Long - thinks the natural chemistry between the pair on new movie 'Going The Distance' has made the film even better.

"It's very rare for me to walk into a movie and have such an honest amazing chemistry with someone; that was such a blessing and a gift and I really felt lucky."

The 'Wedding Singer' star also admitted she has experienced the pain of long-distance love - as depicted in the new film - but believes it is possible to make a romance work even when spending so much time apart.

She added in an interview with Australian newspaper Nine to Five: "I've been in long-distance relationships my whole life so I totally related to this as a woman. I know what I would want to make a long-distance relationship work, such as letters, surprising each other or making plans to do things that make you feel great and alive, and feel really special and think that you're a part of this unit and it's not a phantom thing.

"I think probably one of the real pitfalls of long-distance relationships, is the not knowing all the time and the inconsistency."
