United Kingdom, Sept. 14 -- Graham Norton has denied guests at Taylor Swift and Travis Kelce's wedding had to sign non-disclosure agreements.

The 63-year-old presenter was "so surprised" when the pop megastar invited him to her nuptials during an appearance on his talk show - which led to Graham and fellow guests Cillian Murphy, Jodie Turner-Smith, Domhnall Gleeson, Greta Lee and Lewis Capaldi starring in the Opalite video - and didn't realise he'd be at the "whole thing".

Graham confirmed he didn't have to sign a written contract to say he wouldn't speak about the events that took place during the couple's celebrations at Madison Square Garden in New York in July and didn't see anything wrong with guests being asked not to take picture...
