Move over, Suri - there's a new baby in town.
Beyonce and Jay-Z introduced their daughter, Blue Ivy Carter, in true social media style.
The four-week-old, who shares a birthday and engagement anniversary with yours truly (January 7), has her own official tumblr blog - helloblueivycarter.tumblr.com.
How's that for a superstar welcome?
