She's kept mum so far about her pregnancy, but Sienna Miller's growing belly speaks louder than words.
The 30-year-old actress was spotted at a W magazine reception in New York on Tuesday wearing a slinky black gown that showed off her baby bump.
It looks like Sienna Miller is going to have to start preparing for a new role - mom!
The British actress is expecting her first child with boyfriend Tom Sturridge, a source confirmed to Us Weekly.
It's on-again, off-forever for Jude Law and Sienna Miller. The couple broke up several weeks ago, according to a friend of Jude.
"It is mutual and amicable and they are still friends," the friend said. "It was an entirely an end-of-the relationship decision. It had run its course."
Even law's rep confirmed that the two are no longer together.
Law and Miller were engaged to be married in 2004, but split up in 2006. They got back together in the fall of '09 and had been together since then.
