She wrote: “About last night… happiest of birthdays to this special one @cherylofficial we love you.
“The most gorgeous food set up thanks to my friend Scott the @private_chef_direct who also left me a fridge full of food for the week which means no cooking and enough desserts to satisfy this breast feeding mama and my sweet tooth. If you know you know.”
Earlier in the day, Cheryl thanked her friends and followers on social media for their birthday wishes.
She said: “Thank you so much for all the birthday wishes, I had the loveliest day.”
The pop star, who shares four-year-old son Bear with former One Direction star Liam Payne, had received messages from stars including Queer Eye’s Tan France.
