Initial pregnancy rumours surfaced in January when the press speculated that Sienna Miller and Tom Sturridge were expecting their first child, it took the star's stepmother, Kelly Hoppen to confirm the news.

Sienna has been rocking some impressive maternity fashion of late, cementing her place once more in the style stakes.

Her friends no doubt provided plenty of designer baby clobber back in May when she was thrown a baby shower.

Jude Law's ex has stayed pretty tight lipped about her pregnancy, drip feeding quotes including saying she found her pregnancy 'very exciting'.

She also commented on looking forward to the next chapter in her life adding: "I'm in my second trimester, so I'm I-can-talk-about-it pregnant. It's a nice start to a new decade."

Earlier this year Sienna was seen sporting an engagement ring although the highly private pair have also yet to confirm whether they will tie the knot.

All we can hope for now is that Tom's BFF, Robert Pattinson gets broody and we have the obligatory cute celebrity friend holding the baby! #justsayin
