The Mirror claims Simon will be entertaining Sinitta - whom he dated on and off for 20 years - on his luxury yacht in Barbados despite Lauren being heavily pregnant with his baby.
Lauren has reportedly chosen to spend Christmas Day in the Hamptons, New York, with her seven-year-old son Adam and is happy with Simon's plans.
A source told the paper: “It has been a tough year for Simon and Sinitta.
"Simon and Lauren were both upset when she spoke about aborting his baby and it did rock the boat. But the trio have sorted out their differences and are looking forward to spending New Year together."
