I met both during a little golf matchup between Wahlberg and Kevin Dillon from "Entourage". This was about 2 months ago. Wahlberg seemed a little over confident while the Donald was super charismatic. I really liked Donald as I had friendly conversation with him throughout the day.

Here are the autos I got from them ( I got Kevin Dillon & Jerry Ferrara on an Entourage photo but gave it to my Brother in law)
