Dressed in a pink crop top and pleated denim skirt, the 17-year-old singing hopeful looked rather happy as she posed with her hands on her hips.
Before heading inside, Lauren was approached by fans and she happily signed autographs - she's already living the life of a popstar!
Lauren, who is being mentored by Cheryl Fernandez-Versini on the ITV talent show, put on a brave face despite being upset over rumours of a romance between herself and Only The Young's Charlie George.
This week, X Factor's latest evictee Lola Saunders told Reveal that Lauren has been "hurt" over the rumours.
Lola told us: "I think Lauren was hurt about it coming out, but she sort of knew it was coming anyway because they are so close. They're like attached to each other but it's just because they're really good friends."
This weekend, the remaining hopefuls will be performing songs by either Queen or Michael Jackson. Straight after this weekend's results show, the judges and producers held a last-minute meeting in which they ditched the Disco Fever theme for Queen versus MJ.
