Blue Ivy Carter, Beyoncé and Jay-Z’s daughter, arrived by Caesarean section at New York’s Lenox Hill Hospital Saturday night. Beyoncé’s younger sister, Solange Knowles, dubbed the newborn the “most beautiful girl in the world” on Twitter.

According to the New York Daily News, the musical power couple shelled out $1.3 million to rent out the fourth floor of New York’s Lenox Hill Hospital to ensure a private birth. (Lest any hospital employees be tempted by a six-figure offer for pictures of Blue Ivy, they are all being forced to hand over their cell phones at the beginning of their shifts, the Daily News reported.)

E! News
initially reported the baby’s name as “Ivy Blue Carter,” but Gwyneth Paltrow, a good friend of the couple, took to Twitter to clear up the confusion. (MTV’s RapFix pointed out that Jay-Z broke a lyrical promise by not naming his daughter Brooklyn Carter as he said he would in a 2007 song.)

How did Jay-Z and Beyoncé pick out the name Blue Ivy for their daughter? According to Global Grind, Blue is a tribute to Jay-Z’s three Blueprint albums and Ivy comes from the roman numeral IV, Beyoncé’s favorite number. (But perhaps they were also unconsciously inspired by Alicia Silverstone and Christopher Jarecki’s son, Bear Blu, born last May.) That said, Blue Ivy is an early contender for worst celebrity baby name of the year.

Of course, other Texans have given equally unusual names to their offspring:

Bronx Mowgli Wentz
In 2008, Ashlee Simpson and Pete Wentz named their son Bronx Mowgli, choosing the middle name because they had bonded over their love of the Jungle Book. It remains to be seen if Ashlee’s sister Jessica, due in the spring, will pick a more unorthodox name than that.

Baylen Brees
After winning the Super Bowl in 2010, Drew Brees memorably held up his one-year-old son Baylen, who was wearing a pair of headphones. The name Baylen is a modern creation and one that is reminiscent of baleen, the filter-feeding system in whales.

Ocean Whitaker
In 1990, Forest Whitaker named his first child Ocean. Forest didn’t stick to the watery theme with his later children, who are named Sonnet and True.

Rocket, Rebel, Racer, and Rogue Rodriguez
Robert Rodriguez and ex-wife Elizabeth Avellan named their four sons Rocket, Racer, Rebel, and Rogue. Only daughter Rhiannon got a sensible, if still alliterative, name.

Ima Hogg
The tradition of Texans picking ill-advised baby names stretches back to at least 1882, when James Hogg named his only daughter, Ima Hogg, after one of two heroines in her uncle’s Civil War poem. (Poor Ima. The other heroine she could have been named after was Leila.)
