Uma Thurman and beau Arpad Busson welcomed a baby girl on Sunday.

We honor and praise you, Uma Thurman.

The 42-year-old actor yesterday gave birth to her third child at an undisclosed location, Us Weekly reports. The baby girl was brought into being with help from Uma’s paramour, EIM Group founder, Arpad Busson. The bairn’s name, weight and height have yet to be announced.

Uma and Busson, 49, a multi- gazillionaire “fund of funds” company founder, have had a tumultuous relationship. They got engaged shortly after they began dating in 2007, but broke up in November 2009. Last year, they reconciled, reportedly at her employer Louis Vuitton’s spring/summer fashion show in Paris. (What can I say, Vuitton’s strapless numbers have that effect on couples.)

“Uma was definitely not planning on having another kid. It was a surprise,” Anonymous Source told Us in February, when the pregnancy was announced. “But she's over the moon about it, very excited.”

Uma has two children with her ex-husband, Ethan Hawke, Maya, 13, and Levon, 10.

Her pregnancy hasn’t stopped her from doing pr for her new film, the Guy de Maupassant adaptation Bel Ami, in which she plays one of Robert Pattinson’s 548 or so lovers (a list which includes Christina Ricci and Kristin Scott Thomas).
