The actor, who played Cyrus' dad in The Last Song, was thrilled to learn his onscreen daughter had become engaged to Australian hunk Hemsworth, who she met while working on the romantic movie.
Kinnear has given the couple his seal of approval ahead of their wedding, and wants to send them back to the picturesque Georgia city where their relationship first blossomed.
He tells E! Online, "I'll give them a week on Tybee Island. They can go back to the place where it all started. The truth is you can get a hotel there at a very reasonable cost. So I keep my expenditures down and I'm extending a nice gift as well...
"They worked together very well on that movie, but I didn't realise how well when were doing it. It's great for them. They seem very happy."
