The film starred Kevin Costner as Frank Farmer, the bodyguard who saves Whitney Houston's character, Rachel Marron, from a dangerous stalker.
And sources close to former TOWIE star Lauren say she loves how protective Jake is.
"She's told everyone their romance reminds her of the film The Bodyguard," says our insider. "He makes her feel safe."
Lauren, 28, and Jake, 26, met three years ago, but split in 2013 after a series of rows. They reunited officially in June and have since gushed about their future, saying they want to have children and marry.
Lauren has had a rocky road to true love. She became engaged to her co-star and childhood sweetheart Mark Wright – who she dated for a decade – in 2011, but they split shortly after and Lauren was devastated.
He went on to marry actress Michelle Keegan and Lauren met Jake.
Friends say he's since turned his life around and Lauren is convinced she's met 'The One'.
"Lauren fell hard with Jake, she couldn't walk away from him," says the source.
"He's a totally new man now. She says he's showed her what true love is and that he'll still love her when she's old and wrinkly and won't ditch her for someone prettier or more famous."
