The Strictly Come Dancing star reveals in her Mirror column that she likes the idea of reliving her teen years by taking her daughters to Lulworth Castle from July30th - August 1st 2010 in order to see The Human League perform.
We think the kids may enjoy the event's now legendary fancy dress parade more than watching The Human League.
This year's theme is fairy tales and Camp Bestival's organisers are encouraging festival goers to make their fancy dress costumes as weird and wonderful as possible.
Expect to see some truly bizarre costumes throughout the weekend, before they come together for what promises to be a truly memorable fancy dress parade on the final day of the festival.
If Tess does want to join in the fun by wearing a fairy tale fancy dress costume, we think she'd look great as Little Red Riding Hood or Snow White - but perhaps she'll shock everyone by ignoring her image and turning up as the Big Bad Wolf.
