"Friends With Benefits" star Mila Kunis sparked rumours about an engagement to boyfriend Ashton Kutcher after she was spotted wearing a simple gold band on ring finger.
Kunis, 30, and Kutcher, 35, first started dating in April 2012, and have been tight-lipped on their relationship ever since, reported Us magazine.
The pair recently caught kissing during a vacation with Princess Beatrice and her boyfriend Dave Clark in Saint Tropez, France.
The "Jobs" actor is yet to finalise his divorce with actress Demi Moore before walking down the aisle with Kunis.
