Joe Jonas can't escape his ex-girlfriend - Taylor Swift will perform a duet with the Jonas Brothers as part of the siblings' upcoming 3D CONCERT EXPERIENCE film.
Swift was dating Jonas when she toured with the trio last year (08) - but the bitter teen went public with their split after the pop hunk dumped her over the phone.
By then, she had already recorded a duet with the Jonases, which will feature on the soundtrack to their new movie.
Another reported Jonas Brothers flame and touring pal, Demi Lovato, also appears in the movie.
