Michael Phelps Reveals Why He Kept Marriage To Nicole Johnson A Secret 

Michael Phelps has finally confirmed his “hush-hush” marriage to longtime girlfriend Nicole Johnson – and is revealing why he kept it secret.

“I’ve been married for a while. A couple months. I had to keep it a secret from y’all. I had to keep it hush-hush from you guys,” the Olympic gold medal-winning swimmer said during a Facebook Live video while out on a golf trip on Thursday.

“But Nicole and I are married, we are officially married and now we are getting the chance to kind of kick it and hang out now.”

Naturally, the questions began pouring into Phelps’ comment section. And when asked why he kept the marriage a secret, Phelps said, “Just because.”

He also hinted that his 5-month old son Boomer may be getting a younger sibling.

“Thank you for the beautiful comment. Baby number two may be coming soon. Who knows, though?” he teased.

The couple tied the knot in a secret ceremony on June 13 in Paradise Valley, Arizona, PEOPLE confirmed after obtaining a copy of their record of marriage.

The ceremony was officiated by agent and close friend Peter Carlisle, who often posts photos of Phelps, Johnson and little Boomer.

During the Rio Olympics in August, Phelps told PEOPLE that he and Johnson had set a date for the wedding, noting that it would be later in the year. However, it seems the two had already been married for more than two months at the time of the Aug. 23 interview.

“I really can’t wait to get married. It will be a small destination wedding later this year. It’s the next big milestone I’m looking forward to,” he said.
