The reality TV star and her professional skate partner Michael Zenezini were chosen to leave the competition by the show's judges, following a 'safety skate' against television presenter Anthea Turner and partner Andrew Buchanan.
Anthea and Lauren found themselves in the bottom two once the public vote had been combined with the points given to the couple by the show's judges.
All four of the show's judges voted to keep Anthea in the competition, describing her 'skate-off' performance as "elegant" and "beautiful".
Speaking following the result, Lauren remained upbeat, saying:
I'm gutted but I'm ok. I've met some amazing people that I'm always going to keep friends with now. I've had a great experience and I've had fun.
Earlier on in the night, Lauren's first skating performance was blasted by judge Jason Gardiner who said he was "disappointed" by her efforts and that they had "as much sensuality of a walrus on ice."
Earlier former rugby star Gareth Thomas and his professional partner his partner Robin Johnstone wowed the judges with their performance, which took them to the top of the judge's leader board:
Judge Karen Barber commented: "It was a very powerful track and you performed it powerfully. The skating content was fantastic."
Gardiner added: "I have to say it wasn't a bad opening. I was expecting you to be a disaster, really, given that you're a rugby player. What I did get was somebody that was moving very confidently on the ice. You actually had really good speed."
Meanwhile comedian Joe Pasquale and partner Vicky Ogden found themselves at the bottom of the judge's leader board after the funny man tripped on his skates and went flat on his face during his 'Flash' performance.
