Growing Pains dad Alan Thicke plans to take a wife for a third time, as the 58-year-old actor is heading to the altar with his longtime girlfriend, Tanya Callau, says his publicist.
The two will marry in Cabo San Lucas, Mexico, on May 7, according to the rep.
“I’ll be on my third honeymoon, so I’m more of an authority than I care to be,” Thicke, who played TV dad Jason Seaver on ABC’s Growing Pains from 1985 to 1992, quipped in a statement.
Thicke’s previous marriages ended in divorce. They were to Gina Tolleson, a freelance TV reporter as well as Miss World 1991 (they were wed from 1994-99 and had one child), and to singer-actress Gloria Loring (1970-83, two children).
