Paris Jackson, 16, is rumoured to be pregnant by her new boyfriend.
According to sources in the US, fans spotted the late Michael Jackson's daughter in a restaurant making a toast with water instead of wine and hiding a 'prominent stomach bulge'.
The Daily Star newspaper reports one observer saying: "I saw her at dinner and she twice made a toast drinking water instead of wine.
"That and the prominent stomach bulge got people talking. It's highly unusual to toast with anything but a full glass of wine"
The skeptic in us feels there may be another reason for Paris's booze free toast - her age. She's only 16 and you have to be 21 to buy alcohol in America.
So is this a case of fans getting their knickers in a twist over nothing?
A spokesman for the teen refused to either confirm or deny the rumours, simply saying: "I do not comment on her personal life."
Story continues after the video.
News that Paris may be expecting her first child comes just days after she was reportedly spotted looking at engagement rings with her beau. Paris has so far managed to keep her boyfriend's identity under wraps.
The newspaper added that friends of the couple are 'convinced' an engagement is inevitable.
A source said: "She's madly in love with him."
Paris has stayed away from the spotlight for the past year following her attempted suicide last June.
She has since been given the all-clear from doctors after spending some time at a therapeutic boarding school.
