Dustin Johnson, Gretzky expecting

Dustin Johnson and fiancee Paulina Gretzky are having a baby.

Gretzky posted a photo on Instagram late Tuesday announcing the news.

The news was confirmed by Johnson's agent at Hambric Sports. The daughter of hockey great Wayne Gretzky did not say when they were expecting. The two announced their engagement in August 2013.

Johnson is on a leave of absence from the PGA Tour. Golf.com reported in August that Johnson was suspended for six months by the PGA Tour after testing positive for cocaine. The tour denied the report, saying only that Johnson had taken a voluntary leave.

Wayne Gretzky publicly showed support for Johnson, telling radio station SN590TheFan in Canada earlier this month: "Obviously, life isn't perfect. He went through a tough time. As he said to me, 'It's going to make me a better person. And more importantly, a more responsible person.'"

Johnson gave up his spot on the U.S. Ryder Cup team during his leave. The event takes place this week in Scotland.
