Timberbaby

Before Jessica Biel and Justin Timberlake have even confirmed a pregnancy, fans have already coined what's sure to be a ridiculously good-looking baby-in-alleged-utero the "Timberbaby." Do we sense the title for another hit song in the future?
Royal Baby

While this nickname isn't particularly creative, it is fitting. Royal fever reached a frenzy when it was announced that Prince William and Kate Middleton were expecting their first child last year and the public just couldn't get enough details about HRH Prince George. The #royalbaby hashtag took Twitter by storm and graced headline after headline. Now with Royal Baby No. 2 on the way, we're sure to expect more of the same.
The Gosbaby

Remember those dramatic fan reactions to the announcement that Eva Mendes was pregnant with Ryan Gosling's baby? They're nothing compared to the Terminator-esque Internet nickname of "The Gosbaby." (i.e., "The Gosbaby is finally here!") Personally, we think the parents' chosen name of Esmerelda is far lovelier.
BabyYe

Coined "BabyYe" after dad Kanye West's nickname of Ye, BabyYe was the subject of much online speculation—mainly about what her name was going to be. And her parents did not disappoint with the totally bizarre name of North West.
Alien Baby

Not the nicest of nicknames but, hey, who said the Internet was nice? When naysayers started doubting that Katie Holmes was really pregnant, all sorts of theories began to pop up, including the surprisingly popular one that the baby she carried was not a human, but an otherworldly being instead. As we all now know, Suri is real and as human as they get (you know, minus all the designer clothes and jet-setting lifestyle).
#dembabies

While this totally sounds like something coined by anonymous Internet peoples, #dembabies was made up by Mariah herself to describe her impending bundles of joy while she was preggers ahead of a "20/20" special.
Blanket

Yes, Blanket. And while many of us may think this was some bizarre nickname dubbed by the public after the infamous dangling off the balcony incident, it was dad Michael Jackson himself who came up with this gem of a nickname. The late Prince of Pop intended it to be a term of endearment so his son would always feel blanketed with love. Get it?
