Beyonce and Jay-Z have yet to give us a visual glimpse of their newborn girl, Blue Ivy Carter, but on Monday they did dish out some revealing ear candy in which we hear the infant for the first time.

A new Jay-Z song — “Glory” (listen below) — features Blue Ivy at the end of the track after the proud poppa raps,

“Words can’t describe what I’m feeling for real. Baby, I paint the sky Blue. My greatest creation was you.”

Baby Ivy was born sometime on Jan. 7. She is reportedly named after two album titles: Jay-Z’s The Blueprint and Beyonce’s 4, which is IV in Roman numerals.

Jay-Z announced the song Monday via a tweet, which includes a link to the track on his web site Life + Times.

Blue Ivy made a name for herself before she even had a name or was born. At the end of a performance at the MTV Video Music Awards, Beyonce confirmed her pregnancy by dropping her mic, unbuttoning her top and rubbing her baby bump. The “bump” moment broke Twitter’s tweets-per-second record at the time with 8,868 tweets per second. However, two unrelated events have since surpassed the “bump” in the record books.

While the weekend birth didn’t reach the buzz level as the bump did at the VMAs, Twitter did experience a significant spike. Social analytics firm Simply Measured told Mashable that tweets per minute peaked at 2,379 tweets at 11:15 p.m. PT on Saturday, which is a “healthy number for a non-televised, rumor driven event.”

The chart below shows the rise in the mentions of “baby,” “Blue” and “birth.”

Hip-hop pioneer Russell Simmons was the first celebrity to congratulate Beyonce and Jay-Z via a tweet, according to Simply Measured. Other big-name Twitter users followed suit. Here is a list of some of the most-followed Twitter users who mentioned “Beyonce” during the time period measured above.
