Tiesi is recently divorced from NFL quarterback Johnny Manziel.
Neither she nor Cannon have publicly commented on the nature of their relationship or a possible child.
Cannon made headlines last year after he welcomed four children within 14 months. He is a father of seven children with four mothers, including 10-year-old twins he shares with his ex-wife, superstar Mariah Carey.
“I come from a big family, I have several siblings, being raised in an unorthodox family by my grandparents at times, I’ve experienced such a wide range of upbringing that I have such a love and passion for kids and family. I want a big family too,” he said. “The Lord has blessed me with what I asked, but ask and you shall receive. “
CNN has reached out to reps for Cannon for comment.
