Griff has said Taylor Swift sent her a note and flowers to wish her good luck for her performance at the Brit Awards.
Speaking on the red carpet, the British singer-songwriter said she was "so nervous" to be performing at the ceremony.
She said she will be "lost for words" to see Swift at the O2 Arena in London.
Griff added: "In my hotel room, some flowers arrived and the note said something along the lines of, 'Good luck with your performance, hope I get to say hi. Love from your friend Taylor.'
"And I’m thinking, ‘I don’t think know any other Taylor…'"
Also speaking on the red carpet, Olly Alexander said performing with Sir Elton John as part of the Brit Awards ceremony was a "dream".
He said: "Well we pre-recorded yesterday. So it's me and Sir Elton John, so that is quite iconic.
"It definitely is a dream coming true moment, so I’m very, very excited for people to see.
"I’m excited to watch as well, I can’t wait."
He added: "I can’t believe it’s happening, thank you Brits, thank you Elton, it’s going to be amazing."
