Lindsay Lohan's door was forced open by police following an argument with her Russian fiance at her London home.
The troubled star, 30, was heard shouting on her balcony and worried neighbours called the police after being woken by the argument with millionaire Egor Tarabasov, 23.
In footage obtained by The Sun and filmed in the early hours of Saturday morning, the weeping star shouts: "Get out... It's my house."
A Met spokeswoman said: "Police went to an address in Knightsbridge on Saturday following a report of a woman in distress.
"Officers forced entry to the address. There was no-one inside. They traced the occupants and found them to be safe and well."
Police said that no crime was committed and no arrests were made.
It comes after the Mean Girls star left fans wondering whether she could be pregnant when she posted an image on Twitter from her role in the 2009 film Labor Day.
"Lindsay Lohan labour pains trailer - I am pregnant!!" she wrote.
The star played a woman who pretends to be expecting a baby in the movie. The couple started dating in late 2015 and are thought to have become engaged in April.
Lindsay's publicist has been contacted for comment.
