An unknown thief smashed through one of the star's front windows and stole jewellery and purses currently valued in excess of $15k, but that number is likely to rise once the actress takes full inventory of her missing goods.
Her high-tech alarms reportedly went off as the robber broke in but unfortunately it was not enough to scare him/her off and they continued to make their way through her home and steal her items before bolting from the scene.
Thankfully, the Pretty Little Liars star was not home at the time of the break-in, the publication confirms.
Lucy isn't the first high-profile celeb to have their home broken into in 2018.
Real Housewives of Beverly Hills star Kyle Richards was also targeted by thieves while she was away on vacay.
We're just glad that nobody was hurt!
