The couple will tie the knot on July 21 at the Ritz Carlton in Laguna Beach, Calif., People reports. "It will be a lot of friends and family," Harrison told the magazine. "It started off with about 40 people and it's well over 100 people now. You know how those things go."
The guest list will also include several familiar faces including Counting Cars' Danny Koker, who will become an ordained minister to marry the couple, and Pawn Stars co-star Austin "Chumlee" Russell, who will serve as the ring bearer. "I just had no idea there was so much involved," said Harrison, who says he will be doing a lot of the planning for the big day. "I just thought you got a cake, had a party, buy a keg. But we're getting it done."
This will be the third marriage for Harrison, who has two sons with his first wife, Kim, and one son with his second wife, Tracy.
