Whaletail at British Comedy Awards ceremony

When Katy Perry said that she loves ultra low rise jeans I was skeptical if she was telling the truth but now I am learning that the low rise jeans are more popular among celebs than I initially believed. Check out this video of Kath and Kim in which she wears a really low-waisted pair of pants exposing her thong at the back (often called whaletail by fashion experts).
