This is the incredible moment a 12-year-old girl was surprised onboard a flight with tickets to Adele - only for the singer to find out and serenade her mid gig.<br /><br />Natalie Olson thought was was accompanying dad Christopher, 39, on a work trip to Denver until cabin crew announced she was on her way to Las Vegas to see Adele.<br /><br />The shocked tween's reaction went viral after finance worker Christopher posted it on X, and gathered so much attention Adele spotted it.<br /><br />So just two songs into a packed gig at Caesar's Palace she stopped the show and demanded the house lights be switched on so she could find Natalie.<br /><br />She told the crowd: "My friend sent me a video that I was able to open.<br /><br />"I don't remember the dad's name but there is a dad who posted a video on Twitter today of his little girl Natalie and she's here tonight.<br /><br />"[The video was] on a United Airlines flight and the air hostess over the Tannoy on the plane announced its was her birthday and she thinks she's just going to Vegas with her dad for a work trip but she's actually on her way to see me in concert."<br /><br />After a break for cheers she added: "If they are here can the dad please call?"<br /><br />And after Christopher shouted back she asked for the house lights to be put on before she added: "Where is Natalie? Oh there you are my darling girl.<br /><br />"Happy birthday my darling. And dad - you are the best dad in the world."<br /><br />Then the 4,000-strong crowd joined Adele in singing Happy Birthday to shocked Natalie, who also received a personally signed programme from the singer.<br /><br />The schoolgirl from Cedar Rapids, Iowa, hasn't stopped smiling since the gig on January 26.<br /><br />Christopher said "She was so, so happy. It was unreal.<br /><br />"When I heard her stop and say she had a message, and mentioned United Airlines, I knew it was us.<br /><br />"People just went nuts.<br /><br />"It was absolutely unreal. <br /><br />"She was so happy for the rest of the show.<br /><br />"She's such a huge Adele fan - and Queen and others. She has an old soul."<br /><br />Christopher and wife Kelsey told Natalie she was having a sleepover for her birthday - while secretly they had secured the Adele tickets. <br /><br />"It's the only thing she wanted for her birthday - to go see Adele," said Christopher.<br /><br />"She spent the first day just piecing it all together - all the things we had told her to keep it a secret."<br /><br />He asked the United Airlines cabin crew to break the news over the loudspeaker on the connecting flight to Denver on January 24.<br /><br />The staff member can be heard saying in the now-viral video: "We have Natalie on-board. She thinks she's tagging along to a work event but she is really she is flying to Las Vegas to see Adele perform at the Caesar's Palace which was her one birthday wish.<br /><br />"Could we all wish Natalie a happy birthday?"<br /><br />He said @AdeleAccess - her official X page - saw a video of the announcement on X and replied to say they were looking forward to seeing Natalie. <br /><br />But he didn't know Adele had seen it until she tracked down Natalie during the concert.<br /><br />Christopher added: "Even when we left people were giving her hugs. She was so happy."
