The X Factor winner was booked by England and Liverpool defender Carragher to perform at a surprise party for Nicola's 30th birthday. Team mate Steven Gerrard and his wife Alex Curran were expected to attend the event, held at the Hilton Hotel in Liverpool.
A source told The Sun: "Nicola is a big X Factor fan so Jamie thought it would be fun to book Alex.
"He agreed to pay a five figure sum for her to perform a short set."
