Mary-Kate Olsen has reportedly been spotted looking at engagement rings, sparking speculation she is about to marry.
The former child star has been dating Olivier Sarkozy, the half-brother of former French President Nicolas Sarkozy, for more than a year.
And according to the New York Post's Page Six, they could be about to take their romance to the next level after Mary-Kate was seen looking at rings in LA.
A source said: "Mary-Kate has been seen several times in the last three weeks checking out huge engagement rings at the Neil Lane store.
"She really likes cushion-cut diamonds, and all of the rings she has looked at are over five carats. She has narrowed it down, but still hasn't made a final decision."
Mary-Kate, 27, has been dating Olivier, 44, since early 1012.
The age gap between them has raised eyebrows but the actress and designer told the Wall Street Journal magazine that she isn't worried.
"Everyone has an opinion," she said. "I find it's better to focus on what's in front of you and to keep putting one foot in front of the other."
A spokesperson for Mary-Kate had no comment.
