AceShowbiz - Justin Bieber and Hailey Baldwin's whirlwind engagement in July is shocking enough, but people were sent into a frenzy when it was reported that the young couple get legally married after they were spotted at courthouse in September, sparking marriage rumors just a few months after they got engaged.

The "Sorry" hitmaker and his alleged model wife, however, keep their lips tight as they haven't publicly confirmed or denied the rumors. Recently, however, Justin appeared to confirmed their marriage rumors to a fan, saying, "Yes, we are married."

Whether it was Justin being serious or not remains to be seen, but the Canadian heartthrob is not the only celebrity who tried to to keep their marriages secret and took long to finally confirm the rumors.

Among them was Cardi B and Offset. The hip-hop couple, who famously got engaged onstage in October 2017 during Power 99's Powerhouse concert in Philadelphia, secretly married in September that year. The two remained mum on the big news until the "Bodak Yellow" confirmed it in an Instagram post in June 2018.

"Clueless" star Stacey Dash's marriage to lawyer Jeffrey Marty also come as a surprise to many people. Not until last month people actually learned that the star is now a married woman after tying a knot on April 6 in Florida.

Others kept their happy news for a month or so, some others managed to keep it on the down low for 9 months. Find out who they are in the following list.
