Is Blue Ivy going to be a big sister some day? Maybe – but not anytime soon.
and Jay-Z's little girl
, who was born Jan. 7
, is going to have to wait to welcome a sibling.
Jay-Z, whose 40/40 Club hosted the NBA 2K13 release in New York City Wednesday night, told E! Online
that his wife is not expecting a baby. "Not tonight," he said, "not in nine months – absolutely not."
And just in case there were any further doubts, the rapper added, "Not in one, two, three, four, five, six, seven, eight or nine months."
Maybe one day when Blue herself can count that high!
