It\'s the third time around -- for marriage that is -- for Rick Harrison of \"Pawn Stars,\" who announced his engagement to his Las Vegas-area girlfriend. Rick met DeAnna Burditt, who works in a law office, about a year ago at Vintner Grill in Summerlin, Nev. He gave her a 2 1/2-carat diamond ring two weeks on the hush-hush but announced the news Saturday, the Las Vegas Sun reported. No, he did not get the ring from his pawn shop but he said he was smart about the purchase. \"I\'m practical, so I did get it wholesale from my jeweler friends in our business,\" Rick said. This is Harrison\'s third marriage which he views with optimism, the Sun reported. \"The third time is the charm,\" Harrison said. \"Pawn Stars,\" with Rick Harrison, his father Richard Harrison, Rick\'s son, Corey \"Big Hoss\" Harrison and Austin \"Chumlee\" Russell has just begun filming its sixth season, the Sun said.
