The other she captions, "Third Trimester."

Fans were stunned to find out that she was pregnant but E! News confirmed that she is not.

In one of the photos, her on-screen love interest Tyler Blackburn kissed her baby bump. In the other photo, she wore a "PLL" robe and a full baby bump underneath.

The stars said the bump was just a "food baby" via snap chat. Plus, the photos were taken right after each other so of course she could not have jumped from first trimester to third in just an hour.

Fans were still surprised. Besides, the photos could have been a "Flash Back Friday" post and then a recent photo of how far she is in the pregnancy.

Either way, the joke sparked a lot of buzz on social media. People even thought that the character she plays would be pregnant in the "PLL" hit series.

"The fact that Norman Buckley is in the Preggo Ashley Benson picture makes me wonder if Haleb will be pregnant after the time jump," The Charles D tweeted.

Another fan replied to the post, " I hope so."

It did not take long for fans to find out the truth. Becca tweeted, "Ashley Benson is basically the queen of pranks. NO she is NOT pregnant."

While Jenna tweeted, "I'm actually laughing at how people think Ashley Benson is actually pregnant."

Life and Style predicts that the prank also has to do with a plot twist for "PLL" where Hanna prepares to take on the task of being a mother.

A source tells E! News that the two stars were just goofing around and that Hanna is not pregnant on the show as well.
