It is unclear how long Groban and McQueen have been dating, but the actress has shared photos appearing to show Groban on Instagram since at least September 2022, when she posted an image that appears to show her and the Broadway star on a nature walk.

"'Do you know you're Italian?' - boyfriend to a little tree lizard," McQueen wrote in a caption for the post at the time.
