Mary-Kate Olsen Ring: Engaged Or Married? Sporting Gold Band On Ring Finger At NBA Game (PHOTO)

Mary-Kate Olsen gave the New York Knicks NBA team serious competition at their game on Sunday. The Olsen twin attracted a lot of attention when she and her beau, Olivier Sarkozy, put on a display of heavy PDA during the NBA champions' game against Miami Heat at Madison Square Garden on March 3.

The couple's public display of affection wasn't the only thing that caught everyone's eyes- the Full House star-turned-fashion mogul was wearing a gold band on her left ring finger. The photo sparked rumors that couple are engaged or have already wed. The couple had been seen browsing jewelry in stores in France in January.

However, an insider told Us that while the couple are "madly in love," they are not married or engaged. See a photo of the ring here.

Olsen, 26 has been dating Sarkozy, 43 for nine months. The couple share a $6.25 million apartment in New York City. Sarkozy, who is the brother to the former president of France, is a managing director for Carlyle Group's global financial services division.

The couple was first photographed attending a New York Knicks game in November with his two kids. Sarzoky is divorced and have two children from his previous thirteen-year marriage.

Olsen was asked to comment on their May-December relationship around the time their relationship first went public last year. When asked what she thought of people commenting on their 16-year age difference she said: "Everyone has an opinion."

"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," she told the Wall Street Journal magazine of her romantic life.
