Speaking to Hit 105's Stav, Abby and Matt, the 63-year-old journalist admitted he hasn't see his invite.
'Is he going to have the type of wedding where he invites people from work? Are you going to be showing up on the day,' one of the hosts pressed.
To which Richard responded: 'I have no idea. I certainly haven't received an invitation yet. But I've been away for a couple of days...It could be in my inbox.'
Karl and Jasmine Yarbrough revealed their relationship after the Today host ended his marriage with wife of more than 20-years, former journalist Cassandra Thorburn - to whom he shares three children.
The high-profile couple's engagement became public earlier this year, with Karl confirming the news a few weeks ago.
