They are Sisters, and Kate and Karen Lawler.
The first female winner of Big Brother UK was Kate Louise Lawler, who triumphed in the show’s third season in 2002. It wasn’t long after her spectacular climb to fame that she was offered numerous television presenting and DJing gigs.
When Kate applied to be a competitor on Big Brother, it was her fraternal twin sister, Karen, who encouraged her. There can be no doubt in my mind that her twin knows what she is talking about.
