More from Us Weekly:

It's a boy! Us Weekly is the first media outlet in the world to report that Britney Spears gave birth shortly before 1 p.m. Wednesday at Santa Monica UCLA Medical Center, according to hospital sources.

Us was there as Spears, 23, and husband/aspiring rapper Kevin Federline, 27, arrived at the hospital with a police escort shortly before 6 a.m. and medical staff whisked Spears into a birthing suite.

According to hospital sources, Spears was wheeled into a delivery room about 12:15 p.m. and within minutes the first-time mother had delivered via C-section with Federline by her side.

(A rep for Spears had no comment.)
