Lauren and Jake, a property developer, began dating in October 2012 but they have reportedly decided to call it a day following a string of rows.
Cryptically, Lauren tweeted her fans today (24 December) saying: "Love is the most powerful thing #itsbeautiful #notbewasted #1."
She then posted a message which states: "I crave a love so deep the ocean would be jealous."
Lauren's rep confirmed to Scottish newspaper The Daily Record: "We can confirm that Lauren has split up with Jake and asked him to move out three weeks ago.
"Lauren is OK. She has been through worse and is just focusing on enjoying Christmas and looking forward to what 2014 brings."
Lauren was introduced to Jake through a mutual friend and they moved in together six months ago.
Speaking to Reveal in October, Lauren said that she was not quite ready to get married to Jake - unlike her ex Mark Wright and his fiancèe Michelle Keegan, who got engaged in September.
She said: "[Jake and I] spend so much time together, but in a year you don't know each other, so I think I'll wait for that.
"I'm young. Who knows what the future holds?"
Meanwhile, Lauren has also posted another inspirational message to her Instagram page.
It reads: "Do not chase people. Be you and do your own thing an work hard. The right people who belong in your life will come to you, and stay."
