She's waxed lyrical about the joys of motherhood, proving she's not too shy to wear her love of her daughter on her sleeve.
But it appears that Beyoncé has found another way to express her devotion to her new baby- in jewelry form.
The 30-year-old posted a picture of herself on Tumblr wearing a silver necklace spelling Blue.
Showing only her neck and part of her chest, the photo obscured Beyoncé's face, but gave away her curly honey-blonde hair, and showed her wearing a smart jacket with a silver and white top underneath.
The star wore several other simple necklaces, but the Blue piece took centre spot.
Beyoncé often wears blue clothes, accessories and nail varnish as a tribute to her daughter.
The star showed off her shapely post-baby body on the beach in St Barts last month.
Beyoncé reportedly snapped back to shape in super-quick time thanks to training five days a week with trainer Marco Borges.
She avoids processed fare, and sticks to foods like vegetables and grilled meats to keep her curves in check.
