Country star Dolly Parton has been forced to pull out of an upcoming appearance at the SXSW festival in Texas after suffering continuing back problems caused by her large breasts.

The legendary singer, who is famous for her impressive bust, was ordered to rest for six to eight weeks after cancelling her U.S. tour at the beginning of February (08) as a result of her painful back injury.

That tour was due to have started in Minneapolis, Minnesota on 28 February (08).

Now SXSW festival organizers, who had hoped Parton would have a speedy recovery in time for Friday’s scheduled gig, have confirmed she will not be appearing at the event because of her ongoing health problems.

SXSW kicked off in Austin, Texas on Wednesday with performances from artists including R.E.M. and Van Morrison.
