A caller had called 911 to alarm the cops about violence at Gomez's house, reported Ace showbiz.
The caller had informed the cops in false frantic mode that the 20-year-old's father has shot her mother with a gun and that he was threatening to burn down the house.
This fake call was received by police just hours after they got a similar hoax call informing about a break-in at Timberlake's home.
They said four men have broke into 32-year-old's house and two shots were fired. The intruders then took off after leaving a box with red blinking lights.
