Harrison Ford has lavished praise on his girlfriend Calista Flockhart - thanking her for welcoming him into her family.
Ford met the former Ally MCBeal star at the 2002 Golden Globe Awards and the couple has been dating ever since.
And the Indiana Jones actor is grateful for their relationship, as it has allowed him to bond with Flockhart's seven-year-old son Liam, whom she adopted as a baby in 2001.
Ford insists his time with Liam feels extra special because his other children have all grown up.
He says, "She's brought a child back into my home. My youngest, other than (Calista's son) Liam, is 17. It's a wonderful opportunity to be part of a child's growing up, which is always an endless springtime. You see the blossoming and the growing and the nurturing and the payoff."
And Ford is impressed with his girlfriend's mothering skills.
He adds, "(She's) the best (mother) in the world. She's a mother by choice - she adopted Liam before we met, as a single parent, which is an awesome responsibility to take. She's devoted herself to Liam and has done a really wonderful job raising him. I'm happy to now have a part of the job."
Ford has two children with his first wife Mary Marquardt, Benjamin, 31, and Willard, 29. He also has two children with his second wife Melissa Mathison - Malcolm, 21, and Georgia, 17.
