Television directors have been doing it since the dawn of TV: becoming masterminds at hiding an actress's pregnancy if it's not written into the storyline. From shows like Will and Grace or Frasier, it's always been pretty easy to hand a character a large purse or set her behind a plant (like Hilary Duff on the set of Younger). But in real life, when a celebrity is pregnant and needs to go out and about, it can get a little tricky - especially if they have yet to announce to the world that they're expecting.

But these 10 A-listers have got the game down and TV producers and directors have nothing on them when it comes to hiding their baby bumps. Here are 10 women who managed to be stealth in public during their pregnancies.

10 The Kueen Of Hidden Pregnancies, Kylie Jenner

Fans had their thoughts when it came to why Kylie Jenner suddenly wasn't in the public eye as much as she used to be before they found out the truth: that she was indeed pregnant (with the precious Stormi, who is the star of Kylie's social media account). For months, Kylie managed to keep low-key until the birth of her baby, which she announced on her OWN time instead of a tabloid breaking the news. It was really remarkable.

9 Beyoncé Had Everyone Fooled

When one of the world's most famous celebrities is pregnant, people seem to notice fast, but not when it came to Beyoncé, who managed to keep her second pregnancy (with twins Sir and Rumi) a secret from not just the Beyhive, but from literally everyone outside of her inner circle. She announced her pregnancy with a famous social media photo of her donning a green veil and lingerie in front of flowers.

8 The Cleverness Of Eva Mendes

Actress Eva Mendes and partner Ryan Gosling are the king and queen of privacy. While they came out with their relationship in the quietest way humanly possible, people still didn't know she was pregnant when she was (the couple have two children kept mostly out of the public eye). Mendes ended up retiring from acting after starring in Lost River in order to raise the little ones.

7 Mila Kunis Announced It On Her Own Terms

Fans of That 70's Show were doing metaphorical back-flips when they discovered that Mila Kunis (Jackie) and Ashton Kutcher (Kelso) were in a relationship YEARS after the show wrapped. Fans quickly learned that the two were not only engaged, but that they were also expecting a baby back in 2014.

6 Angelina Jolie And The Concealed Twins

While Brad Pitt and Angelina Jolie's relationship had been out in the open since they met on the set of Mr. and Mrs. Smith, they've managed to keep their personal lives with their children roughly out of the public eye. This was especially the case when Angelina was pregnant with twins Knox Leon and Vivienne Marcheline. The couple was more open when it came to Jolie's first pregnancy, which produced Shiloh.

5 Adele Kept It Quiet

While a lot of the children on this list tend to stay out of the public eye, Adele is notorious for keeping her baby away from the prying eyes of the paparazzi, just as she had when she was sporting a baby bump. The singer kept her pregnancy a secret until just two months before giving birth.

While famous glamour couple Jessica Biel and Justin Timberlake already have a five-year-old keeping them busy, they now have a new addition to their family.

3 Jennifer Garner Hid From The Spotlight

Recently, 48-year-old Jennifer Garner had to shut down rumors that she was pregnant after a photo of her holding a pumpkin (with a smaller pumpkin inside) went viral.

2 Princess Of The North Sophie Turner

The courtship of Game of Thrones alumni Sophie Turner and singer Joe Jonas was a public one since they posted pictures of their cuteness all over social media. When it came down to her pregnancy, though, it was just a party of two (actually three) until they were ready to spill the beans.

1 Billie Lourd Knows How To Keep A Secret

Almost everything about Carrie Fisher's daughter Billie Lourde has been a secret, it feels like.
