The mother-of-one looked so pretty as she made the announcement - wearing bright pink lipstick. HELLO! spoke with makeup artist Lauren D'Rozario, who said Rachel loves a bold lip.

She said: "I've been doing Rachel’s hair and make-up for almost seven years now. Her skin is always flawless so I have the best canvas to work with. Rachel typically loves a soft glam makeup look and isn't afraid to wear a strong lip colour."

She added: "It's a fun maths book, so there's more references to football, cocktails and even vejazzles than you might expect."
