Beyonce Knowles spelled out her love for daughter Blue Ivy in the form of a gold necklace, as seen in a new self-snapped photo from her official website.

In the picture -- featuring the singer's neck and cleavage only -- the new mom, 30, proudly displayed her latest jewelry. It's yet another fun way Knowles has paid tribute to her 4-month-old (with hubby Jay-Z, 42): in February, she had her nails painted blue for her first public appearance since giving birth.

"Check out Beyonce's blue nails called Baker Street by Nails Inc.," Lisa Logan, Knowles' manicurist, tweeted. "I love this color!"

Like her parents, Blue Ivy "is going to be a really bright kid," a source tells Us Weekly of the couple's first-born. "She is laser-focused."

Fashion and beauty aside, Knowles has also been busy rehearsing for her first post-pregnancy show on May 25 in Atlantic City. "We do cardio and plyometric moves like lunges and jumps on and off a bench," her trainer Marco Borges tells Us of the star, who also sticks to whole foods like vegetables and grilled meats.

Says a pal: "She is loving her body!"
