“This over the top behaviour rolling around on the beach is like healing. I feel free and liberated because I felt trapped for so many years.”
Lisa rose to prominence after she appeared on Channel 4's 2008 series of Big Brother with then-boyfriend Mario Marconi, where they became engaged. The duo later tied the knot on another Channel 4 series, The Wedding House, but the relationship fell apart in 2013.
