This is one reason why you should never mess with a pregnant lady!
Olivia Wilde took to social media to put train passengers in NYC on blast for being selfish.
The heavily pregnant star did NOT appreciate being forced to stand up for her whole journey.
So she did what any modern woman would do, and threw some serious shade at her fellow passengers.
See more from her angry subway rant in the clip below. Post continues!

Olivia doesnโt take any schtick!
โNBD able-bodied riders who wonโt give your seat to a GIANT preggo,โ she wrote.
โIโll just stand riiiight next to your head and hope I go into labour.โ
Olivia is currently expecting her second child with husband Jason Sudeikis.

Baby number two is not far away now!
She previously revealed how talented her first child Otis is at playing the drums.
โMaybe itโs a past life thing, I donโt know,โ she said of her cheeky little boyโs talent.
Check out Otisโs mad drum skills in the video below! Post continues.

Little Otis is already a wannabe rock star.
She says Otis is pretty much like a mini Jason, and is raising him to have her values.
โI like to think heโs already a little feminist,โ she says of Otis.
โI want to promote the idea that the definition of feminism is equality and itโs something thatโs not difficult to teach children because they are born with that sensibility.
โThey are only taught to separate people and value them differently once they get older.โ
