Marie Osmond may have just let something slip about her brother Donny that he definitely did not want to reveal!

The reality television competition show “The Masked Singer,” which airs on FOX, has captured the attention of television audience since its debut. The show features celebrities singing in disguise, not revealing their identity until they are eliminated from the competition. Ever since the show premiered, fans have speculated that “The Peacock” on the show is none other than Donny Osmond. These rumors were fueled when the Peacock told the judges that he started performing at the age of five and that he was friends with Michael Jackson.

When they were interviewing Donny’s sister Marie, the hosts of Access Hollywood decided to do some digging to figure out if the Peacock really was her brother. The way Marie responded makes it seem very likely that her brother is indeed the Peacock!

After confirming that Donny did in fact begin his career when he was 5, Marie let slip, “I told him, ‘Why are you giving away such easy clues?'”

As the hosts cheered, Marie frantically tried to backtrack, likely realizing that she had said too much.

“I don’t know!” she exclaimed. “But I know that we started at NBC, which was the peacock.”

It certainly sounds like Donny may really be the star dressed as the Peacock!

Even before Marie’s slip up, fans were pretty convinced that the Peacock was Donny. In a Twitter poll, a whopping 70 percent of users said that they believed him to be the Peacock, with the next guess being Neil Patrick Harris at just 7 percent.
