2012: A year in celebrity bumps, babies and pregnancies

Sienna Miller

Sienna Miller kept tight-lipped about her pregnancy, but has recently spoken out about her love of motherhood. Sienna even joked she has a new understanding of what her breasts are for, as well as posing for a naked portait while pregnant. Sienna has brought her fashion-savvy nature to motherhood, being spotted with a limited edition Missoni Bugaboo buggy shortly after the birth of daughter Marlow. Sienna's actor boyfriend Tom Sturridge must be one proud papa.

Lily Allen

Since news broke that Lily Allen was pregnant for the second time we've enjoyed some classic pregnancy-themed tweets from Lily. From pondering her inability to wear heels and putting heart burn remedy in her Chanel bag, Lily's kept us chuckling. This will be Lily's second baby, after welcoming daughter Ethel Mary in November 2011.

Jessica Simpson

Jessica Simpson had quite an eventful pregnancy. After her nude mag cover was hidden in a US store and Jess shared every detail of her pregnancy, celebville was on full labour alert after she passed her due date. There was a lot of has-she-hasn't-she before the star and husband Eric Johnson shared news of Maxwell's arrival on her website.

Robbie Williams

Robbie Williams certainly has a way with words. After his wife Ayda gave birth, Robbie described it as being like the first 30 minutes of Saving Private Ryan. Nice one, Rob! Robbie has since spoken out about daughter Theodora Rose, or Teddy for short, saying that he hopes she will be nice and polite. Rob has since made our top 10 dads' list after he posted a cute pic of him and Teddy.

Adele

Songstress Adele shocked us all when boyfriend Simon Konecki revealed that she was much further along than expected. It was only a matter of months after her pregnancy anouncement that Adele gave birth. The new mum has yet to be seen out and about and has made no mention of a baby name. In fact, Adele is said to have missed the deadline and faces a fine, oops!

Coleen Rooney

Coleen Rooney has also kept rather quiet about her second pregnancy. After sharing news she was pregnant with her and husband Wayne's second child on Twitter, Coleen's since been tight-lipped. We reckon little Kai is keeping her busy, as they've had a recent trip to Lapland - lucky lad!

Drew Barrymore

Drew Barrymore accidentally revealed she was pregnant when spotted walking out of the doctors with her baby scan pic. After giving birth Drew gave us an insight into her's and husband Will Kopelman's reasons for choosing Olive for their daughter's name and has now shared first baby pics. Drew is all about the giving. We LOVE it.

Jennifer Aniston

OK, so not pregnant or indeed a celeb with a baby, but never has a celeb had more turns in the bump-watch spotlight than Jennifer Aniston. Jen seems to see the funny side of the constant rumours and speculation and even did a spoof advert which claimed she hid her bump under an elastic belt. We like your style, Jen.

Megan Fox

Megan Fox and Brian Austin Green recently welcomed their first son, Noah. Brian thanked fellow actress Reese Witherspoon, who reportedly gave birth on the same day, for helping them go unnoticed into the hospital. Noah's name has already topped a top list for celeb baby names in 2012.

Reese Witherspoon

Speaking of Reese, the plucky actress seems to be quite the secret keeper. Not only did she kind of help Megan Fox, she kept her own pregnancy on the quiet right until her due date was approaching. Reese named the latest addition to her and hubby Jim Toth's family Tennesse and has since been spotted with her little one and a cool buggy.

Peaches Geldof

Bob Geldof's daughter Peaches gave birth to son Astala and boy, have we seen a lot of pics since then! Little Astala has been captured in many a fancy dress outfit along with some cute pics with her dog. Peaches is now pregnant again and expecting her second child with husband Thomas Cohen next year.

Kourtney Kardashian

Kourtney Kardashian gave birth to daughter Penelope Scotland in June, even helping deliver her. Kourtney has since given other mums some tips, sharing advice on what you should pack in your hospital bag. Kourtney and partner Scott Disick also have a son, Mason, 3.

Una Healy

Mum-of-one Una Healy gave birth to daughter Aoife Belle in March. Hubby Ben Foden and Una recently had her christened and often share cute pics on their Twitter accounts. Una's The Saturdays bandmate Rochelle Wiseman announced in November that she's pregnant with her and hubby Marvin Humes' first baby, too.

Kate Middleton

Easily the pregnancy of the year, Kate Middleton and Prince William's news was broken by Clarence House - on Twitter! How cool are they? Kate has since suffered with acute morning sickness, but is said to be feeling better. Congratulations have flooded in for the pair with lots of comments on what wonderful parents they'll make and rumours about the baby name they'll choose. What a year for the Royals, huh?!
