Vine star Tish Simmonds delighted millions of fans this morning when she appeared on BBC Radio 1's breakfast show.
Last night she told her fans she was appearing on the show.
And after an early night last night - 9.15pm - she and mum Dawn were up at 3.30am to catch the train to London.
She and her mum Dawn were invited on the show by presenter Nick Grimshaw after he spotted her six second video clips on the internet.
Tish shot to fame overnight after a clip of her in her mum's car was seen and shared on internet video site Vine by millions across the world.
She said: "It was amazing.
"I had to get up at 3.30am - I just woke up like a shot. We got the train from Huddersfield to Wakefield and then Wakefield to London.
"We got a taxi to the studio and they showed us round and we saw Nick Grimshaw. I said hi to Fearne Cotton."
During the show Nick said he had played a song made by a fan to the X Factor judges - and Tish was over the moon.
She said: "It was amazing. I love the X Factor and I love Simon Cowell."
Simon said the song was a bit short - but Tish said she could do a longer one!
Tish, who hopes to be a voiceover artist, said she made some short films with Nick and the crew which will be on the BBC's website today. She said she and her mum had a look round the BBC gift shop, took pictures with a Doctor Who Tardis and Dalek, and were even spotted by adoring fans in London who asked for pictures with her.
She said: "I've listened to the show - I sound rough! I'd love to do it again."
