Two years after announcing their split, Kutcher and Moore's divorce was finalized this week, which means the actor is free and clear to tie the knot again.
"Ashton and Mila have talked about getting engaged and married for quite awhile," the source said. "He wants to get engaged during the holidays."
"Ashton's been waiting for his divorce to be over for a long time," another friend of Kutcher's said. "He was annoyed it took so long. It was hanging over his head."
Kutcher and Moore were married for six years before reports of infidelity led to a rift in the marriage. Shortly after, Kutcher began seeing Kunis, his former "That 70s Show" co-star in April 2012.
