Hudson broke the news while taping an performance that will air on an upcoming American Idol episode after Wednesday night’s live Top 10 performance show. Prior to her performance, Idol host Ryan Seacrest asked the singer and Oscar-winning actress if she had set a date for her wedding yet.
“Yeah, but it’s a secret,” she told Seacrest, according to People. “I can’t tell anybody.”
Hudson went on to perform her single “If This Isn’t Love” on the Idol stage.
Otunga — a former I Love New York 2 contestant who made to the reality dating show’s Final 3 before being cut by series star Tiffany Pollard — proposed to Hudson with a Neil Lane diamond ring last September.
The couple, who have been dating for less than a year, both are natives of Chicago. Prior to Otunga, Hudson had dated childhood acquaintance James Payton for eight years and been the subject of unconfirmed engagement rumors.
Hudson will be beginning her first-ever solo tour next week. She she will co-headline the tour with R&B singer Robin Thicke.
