Ant and Dec's Saturday Night Takeaway provided an emotional surprise for viewers as the show returned to ITV with a marriage proposal.
The first episode went off with a bang after Daniel Garnham proposed to girlfriend Victoria Haynes, live on national TV, having flown over from New York to pop the question.
The grand romantic gesture has left Ms Haynes "on cloud nine", she said.
"This is incredible," she said. "I don't feel like it's real. I'm sure I'll wake up tomorrow with 100 messages on my phone and it'll start sinking in but at the moment I'm just living the dream."
She added: "It's the best day of my life, absolutely no question."
Ms Haynes's parents were on stage with them as she tearfully said yes.
Mr Garnham, who is from Eastbourne but lives in New York and works with the Blue Man group performance show, said he had asked his bride-to-be's father for his blessing last October.
Speaking shortly after the proposal he said: "It's just starting to sink in a little bit. It was a weird experience. It was an out of body experience but it was one that I've been wanting to do for a very, very long time so it was great."
Ant and Dec had already shocked Ms Haynes, an office temp from Northampton, with hidden-camera footage of her parents following her and Mr Garnham on their travels abroad last summer.
The Geordie duo surprised the family further by revealing they would send all four of them to Ibiza on a celebratory holiday.
Asked after the show about the kind of wedding she might like to have Ms Haynes said: "One with all the important people there. Something with everybody that I love there, that's the most important thing."
Ms Haynes, who is currently living in the UK and has been with Mr Garnham for two-and-a-half-years, said she would love to move to the US in the future.
Social media users described the proposal as "amazing".
One, named Gem, tweeted: "That was the most sweetest (and elaborate) marriage proposal I think I've ever seen Great start to the show! #SaturdayNightTakeaway".
Another Twitter user, Emily, said: "OMG that engagement was amazing! I was fangirling - that's proposal goals to get engaged on #SaturdayNightTakeaway".
