There's that ring again.
Mary-Kate Olsen flashed the familiar diamond ring while attending the Louis Vuitton show as part of the Paris Fashion Week Womenswear Fall/Winter 2014-2015 on Wednesday in Paris, France, with her sister Ashley.
Mary-Kate has yet to confirm the rumors that she is engaged to 44-year-old beau Olivier Sarkozy, but continues to add fuel to the fire after being spotted multiple times with the ring on that finger.
But if they lovebirds are ready to say "I do," it seems that the pair is still on a different timeline with regards to how soon the twosome plan to walk down the aisle.
E! News has learned the former actress wants to "marry and settle down as quickly as possible," while Olivier wants a "nice long engagement."
"If they are engaged, they haven't announced it to family and friends in France yet, but who knows," an impeccably placed source in Olivier's home city of Paris tells us.
"All we know is that Olivier will want a nice long engagement—he's been through a marriage already and had lovely kids, so he knows what it's all about," the source revealed.
Sarkozy and ex-wife Charlotte Bernard split in 2010 after 13 years together and have two children, son Julien, 12, and daughter Margot, 10.
