The reality television star caused concern after failing to catch a flight to Germany, where she was scheduled for an eight-city tour to promote her latest album.
According to TMZ, her manager called her several times with no response, sparking fears that she was missing or had self-harmed.
Tequila, 30, was recently hospitalised with a brain aneurysm after a suicide attempt, and has a long history of substance abuse and depression.
Police were called to investigate at the singer's LA home after she didn't respond to knocks on the door by her assistant.
Officials emerged minutes later from her home after speaking with her, with one cop saying: "I don't know why we were called here."
There is still no word on why Tequila missed her flight.
