The 31-year-old singer is said to have snubbed a glass of champagne at a recent birthday party and according to In Touch Weekly, it is because she and fiancé Eric Johnson are expecting their first child.
“She’s already having kooky cravings,” said a source, claiming she has developed a taste for nacho chips dipped in chocolate, “which satisfy her urge for salty and sweet.”
The couple are due to say ‘I do’ in November and the insider added that Jessica is not due until spring so the wedding will go ahead as planned.
They think the baby is, ‘the best wedding gift ever’, added the source.
