London, Sep 6 - Hollywood actress Scarlett Johansson has confessed that she dreads heading out on musical tours because she suffers from stage fright.

The actress-singer has recorded a new album with music collaborator Pete Yorn, called 'Break Up', and she fears success will lead to a series of live shows she'd rather not think about, reports Star Magazine UK.

'I have terrible stage fright. I've never had to sing in front of a live audience, other than some back-up vocals,' she said.

'It seems incredibly revealing, very different from making a red-carpet appearance, where the glitz and glamour of movie stardom... can mask any sort of insecurity,' she added.

If pushed, Johansson says she might consider dressing up for a concert: 'I'd dress like a character from The Dark Crystal.'

'Break Up' isn't Johansson's first musical effort - she released an album of Tom Waits songs, called 'Anywhere I Lay My Head', in 2008.
