Robert Rinder appeared on Thursday's (August 28) installment of This Morning as he chatted with presenters Rylan Clark and Josie Gibson.
As he got comfortable on the sofa, Rylan exclaimed that it felt "weird" to interview him, considering they're such good friends.
The pair joined forces last year for their own BBC Two show, Rob and Rylan's Grand Tour.
The three-part series saw them visit some of Italy's greatest art treasures in destinations such as Venice, Florence and Rome as they followed in the footsteps of 19th-century romantic poet Lord Byron and other Grand Tourists.
Due to the popularity of their show, Rob and Rylan travelled to India last year to film the next few episodes.
However, Rob will also be fronting a brand new show with Hollywood star Elizabeth Hurley in Channel
