The 25-year-old former 'Made in Chelsea' star attended the launch of Hogwarts in the Snow, at the Warner Bros. Studio Tour London - The Making of Harry Potter on Wednesday (22.11.17), with her boyfriend James Dunmore, 28, but he panicked at the talk of engagement and told her to scrap the thought of marriage from her mind.

During their visit, James asked a guide whether people get married in the Great Hall, but when the guide said there aren't any marriages but people do get engaged, James turned to his girlfriend and said: "don't go getting any ideas."

Lucy was also given a wand which was designed the same as the Dark Lord Voldemort and her boyfriend joked that it was "about right for her".

The studios - which brought to life the eight 'Harry Potter' movies - saw a number of other celebrities attend including Alexandra Burke and her 'Strictly Come Dancing' partner Gorka Marquez, 'Great British Bake Off' winner Candice Brown and Rebecca Ferguson.

'Harry Potter' star David Tennant - who played Barty Croach Jr in 'Harry Potter and the Goblet of Fire' - was also seen donning a Christmas jumper.

Former 'X-Factor' contestant Rae-Elle Williams, who was kicked off the show last weekend, reunited with Grace Davies and the two shared a hug in front of the Yule Ball stage in the Great Hall.

The studio tour featured the Yule Ball for the first time, which debuted in 'Goblet of Fire', and was inspired by the Brighton Pavilion.

The iconic Great Hall was transformed for the festive season which snow-covered Christmas trees, icicles and an orchestra of magical instruments.

The orchestra itself is made up of musical instruments painted by the Prop-Making department to match the silver of the Yule Ball decoration.

Hogwarts in the Snow will run from November 18 to January 28.
