Happiness Moment: Sienna Miller Welcomes First Child

The ultra private couple has been dating for about a year and showed signs of an engagement back in February, when the actress was spotted with a hefty diamond ring on her left hand. However, they have yet to comment on their plans to marry.

However, the actress, who had a tumultuous on-again, off-again relationship with Jude Law for years, did confirm her pregnancy in British Vogue this spring. She said in the interview: "Even though I'm under strict instructions not to say anything as it would completely defeat the point of everything I've tried to achieve in the last eight years. I'm feeling fine...It's all progressing nicely and it's very exciting."

Congrats to the happy couple!

Sienna Miller is the latest addition to the Hollywood mom club! The actress and fiance Tom Sturridge reportedly welcomed their first child this weekend, according to Us magazine.

No details have emerged as far as the baby's gender and name, but we're sure those tidbits will follow shortly.
