Rapper Jay-Z is over-protective of his baby daughter Blue Ivy, says singer Alicia Keys. Keys says the rapper was not pleased when her two-year-old son, Egypt, went to give 13-month old Blue Ivy, a kiss. "Egypt kissed Blue, and I don't think Jay liked it very much," showbizspy.com quoted the 32-year-old as saying.

She added: "He called my husband and he was like, Watch your son."

Blue Ivy is Jay-Z's daughter with Beyonce Knowles.
