Lost actress Emilie De Ravin wants her wedding to fiance JOSH JANOWICZ to be spontaneous, because bringing their families together for one special day is proving impossible.

The 23-year-old beauty, who plays CLAIRE LITTLETON in the hit TV plane crash drama, was delighted by her fiance's romantic proposal, but she has no immediate plans to start a family like her character.

She says, "It was very romantic. Josh had planned it all - he'd even bought the ring.

"I am very excited, but I think the wedding will have to be impromptu because it is almost impossible to get all our families together in one place.

"We have a dog, BELLA, who is a prefect baby substitute for now.

"She's a poodle with large flappy ear - she is really unique."
