Sienna Miller is one of many pregnant celebrities right now, but that doesn’t make the bun in her oven any less special. Awww.

The 30 year-old actress confirmed her pregnancy with Vogue UK, finally breaking her silence on her growing bump. “I’m in my second trimester, so I’m I-can-talk-about-it-pregnant, even though I’m under strict instructions not to say anything,” Sienna said.

In the past eight years, Sienna has been fighting for her privacy rights after a paparazzi stalked her repeatedly. She was also a victim of Rupert Murdoch’s News of the World hacking scandal.

“[Speaking about my pregnancy] would completely defeat the point of everything I’ve tried to achieve in the last eight years,” Miller continued.

But I mean, you’re already talking about it, so you might as well give us something else to go on. She did say: “I’m feeling fine...it’s all progressing very nicely and it’s very exciting.”

So I guess that’s something. But anyway, a source close to the actress says that being pregnant has made Sienna grow up “overnight.”

“All she thinks and talks about now is buying a new house, decorating and baby stuff.”

Sounds grown up enough to me. The source added:

“Sienna used to love partying, but now she’s yawning by 11pm if she goes out! “Sienna’s glowing. She hasn’t put on too much weight anywhere else, so she’s got a gorgeous neat bump,”

Yes, her bump is very organized. Sienna looks great, and this will be her first time to be a mom. The father is her fiancé, Tom Sturridge.
