At the age of 14, Holly was discovered by Storm Modelling Agency whilst on a school trip. In just a few years she had been the face of Rimmel, the body of Pretty Polly and appeared on the covers of various women's magazines. Holly has appeared in numerous TV commercials and proved herself as a natural in front of the camera. It was then she decided that TV presenting was the job for her.
Joining a friend for a casting led Holly to land her first job in Television when a Production Company were looking for a team of fresh and young presenters to host their new Saturday morning show, S Club TV.
In 2003, Holly recorded Call The Shots and Xperi-mental, along with coverage of Fame Academy (BBC) and Xchange (CBBC).
In 2004, Holly co-presented the Game Star Awards (ITV1), Junior Eurovision (ITV), CD:UK (ITV), and the 19 Management's Anniversary Party at the Royal Albert Hall in London.
2005 was a busy year, as she continued with Ministry of Mayhem (re-named Saturday Showdown) and regularly guest presented CD:UK. She also co-hosted the ITV2 coverage of Celebrity Wrestling: Bring It On, and recorded a brand new show for CiTV called Feel The Fear.
2006 started with a bang as alongside recording Saturday Showdown each week, Holly co-presented ITV1's ratings smash, Dancing on Ice. In February she co-presented ITV2's coverage of the BAFTA's Red Carpet and in May Holly recorded a new ITV2 show Lip Service which brought together all the weeks' gossip and clips from celebrity chat shows around the World.
