Shortly after the legal proceedings began to end his marriage, the 62-year-old actor's mug started showing up on 30-year-old model Santa Auzina's Instagram page, accompanied by hashtags like "#mylove" and "#soulmate."
Based on Santa's Instagram pics, she and Dennis seem to have started seeing each other around July, when Dennis and the French Canadian beauty were photographed snuggling up to one another at the Atwater Cocktail Club in Montreal, where he's been filming "The Art of More."
Since then, they've dispensed with keeping what appears to be a romance under wraps and have been enjoying -- and posting about -- their PDA-stuffed bicycle and golf outings, sightseeing tours around town and get-togethers with friends.
Multiple trips to Montreal's Notre Dame and a night out on the town for a Toots and the Maytals concert have also been on the pair's itinerary.
Dennis and his wife filed for divorce in June, marking their second major split since they wed in 2004.
"After careful consideration, we have decided to end our 12-year marriage," they said in a joint statement earlier this year. "The decision was made amicably and with mutual respect toward one another. We will always remain great friends and devoted partners in raising our children."
They share 8-year-old fraternal twins Thomas and Zoe. It was the third marriage for Dennis, who also has a 24-year-old son with Meg Ryan, actor Jack Henry Quaid.
