Knight initially played coy when “ET” host Lauren Zima asked him if he and Rodriguez had married after Knight called Rodriguez his husband.
“We may have, we may not have,” the “Step by Step” singer said with a smile, although Zima later pointed out that he was wearing a flashy wedding ring.
Knight told People last year that he considered eloping with Rodriguez after Covid-19 halted their wedding plans.
The pair is based in Massachusetts, where they film the HGTV series “Farmhouse Fixer.” On the series, Knight renovates farmhouse-style homes for clients that have included his mother and extended family, he told “ET.”
Knight recently returned from a New Kids on the Block tour with support from contemporaries like Salt-n-Pepa, Rick Astley and En Vogue.
