Marie Osmond is taking a third shot at marriage – with someone she knows well.
The singer is set to remarry Stephen Craig, her first husband, Wednesday in Las Vegas, a source tells PEOPLE. They’ll tie the knot at the Las Vegas Mormon Temple.
The couple have one son, Stephen, now 28, together.
The singer walked down the aisle again in 1986, marrying music producer Brian Blosil, with whom she had 7 children, before divorcing in 2007.
News of Osmond’s remarriage was first reported by Access Hollywood.
