Get lost, Memphis Bleek: Jigga has a new sidekick. The hip-hop monarch celebrated the birth of his and Beyonce's brand-new girl, Blue Ivy Carter, with an ultrasweet rap lullaby featuring the Notorious B.I.C. herself crying in the background. "The most amazing feeling I feel/Words can't describe the feeling for real," he raps. "Baby, I'll paint the sky blue/My greatest creation was you." Awwwww!
