Beyoncé and Blue - Much ado has been made of Bey’s cute nods to her baby girl Blue Ivy by wearing cobalt nail polish, but really the "Diva" mom has had the blues all over since her pregnancy (maybe she was sending the hint all along!).  (Photo:  Mike Coppola/Getty Images)

Out & About - Mom kept her love for blue on top while making a trip to her office in New York (October 24, 2011). Her bright leather jacket and print scarf helped hide Blue Ivy in bump form. (Photo: Three Kings/WENN.com)

Diva - Who said pregnant women can’t be hot!? Bey had the girls on display in this black and blue sheath when she stopped by her pal Gwyneth Paltrow's movie set (October 14, 2011). At this point, she had become an expert at hiding her protruding belly from the cameras: notice the cover up by way of her Birkin bag and blue shawl. (Photo: CWNY/Fame Pictures)

Haute Pop - Bey modeled a haute look that can work for women expecting or not when she teamed a bright cobalt bag and towering blue suede shoes with an otherwise all-black look while out in New York (October 19, 2011). (Photo: CWNY/Fame Pictures)

Midnight - All black everything kept Beyoncé looking trim when she hid her belly on the streets of New York (November 8, 2011), but she styled the look with a navy-colored croc purse that was big enough to be a diaper bag! (Photo: CWNY/Fame Pictures)

Print This - During her pregnancy, Beyoncé slipped into graphic-print tights to give her all black pairs a rest. We loved the vibrant print on these ASOS "Ikat" leggings she wore in New York on November 29, 2011 (even better, she scooped them up for $21.82!). (Photo: Humberto Carreno / Startraksphoto.com)

Say It Loud! - Once B.I.C. was born, Beyoncé totally stepped up her blues. The proud mama went head over heels for the hue in a Monique Lhuillier sequined gown accessorized with cobalt drop earrings, a ring, bracelet and the color was even on her toes! (Photo: Courtesy beyonceonline.com)

Signs - Bey threw up stylish hand signals on a post-baby date to the Knicks game with hubby Jay-Z. She repped her man’s Brooklyn hometown with a “Brooklyn Bridge” ring by Noir Jewelry but had us all swooning with the Nail Inc “Baker Street” polish she sported in honor of her newborn baby girl.

Baby Makes Three - The whole Carter Family had the blues when they stepped out for a lunch date at Sant Ambroeus in New York City on February 25, 2012. Blue Ivy was wrapped in a blue blanket, dad wore indigo denim and mom beat the cold with a navy jacket and kept up her perky cobalt manicure. (Photo: Teach/FameFlynet Pictures)
