The couple appear together in new commercials for menswear brand London Fog, reported Women's Wear Daily.
A spokesperson for the campaign said, "We wanted a couple, and they to us really represented a modern iconic Hollywood couple. (Harris and Burtka) are very much a Hollywood iconic couple of today.
"We have a smart consumer. We think they'll get it. We don't think there will be an issue... I think it will play well. It's a beautiful, powerful, intimate moment, and it's still a fashion campaign."
