Adriana Lima's Second Baby Born

And baby makes four!

Adriana Lima has given birth to a healthy baby girl, confirms Us Weekly. The Victoria's Secret model welcomed Sienna at around 1pm on Wednesday in New York City.

It's the second child for Lima and hubby Marko Jaric, who already are parents to Valentina, age two. Lima tweeted late Wednesday night, "Marko and I are overjoyed to welcome Sienna into our family and Valentina is looking forward to becoming a big sister!"

Sienna arrives six months after Lima made the big announcement, and the timing worked pretty perfectly: between then and now, there were no Victoria's Secret shows to walk in nor urgent ad campaigns covers to pose for. In fact Sienna has made her debut just as New York Fashion Week wraps up, which we assume means she and her magically elastic model body will be back on the runway for the Victoria's Secret Fashion Show by November.

Congratulations to the happy family! We can't wait to see pics of little Sienna.
