Reese Witherspoon and Jennifer Garner perfectly shutdown false pregnancy rumours on Instagram by discussing their "imaginary" new additions.

The stars’ response came after a magazine recently announced that the two actresses were expecting and that their “baby bombshells” had left them both filled with “shock and joy”.

In an Instagram post of the OK magazine cover, Witherspoon mocked the news with the caption: “Hey Jennifer Garner! Can we raise our imaginary babies together?”

Garner responded to Witherspoon’s post, which was liked more than 500,000 times, in the comments, where she agreed that they would be “the cutest imaginary family”.

“I’ll just go ahead and move in now,” she added.

Other stars also joined in on the conversation, with Ali Wentworth offering to throw a baby shower for the actresses and Sarah Michelle Gellar commenting: “Only if I get to imaginary babysit,” to which Witherspoon asked: “Will you be the imaginary godmother?”

The post prompted fans to offer their fake congratulations as well, with many acknowledging the fake stories in tabloids.

“Oprah once said on her show that every once in a while she would go to the grocery store to read what she had been up to," one person wrote.

Despite the news being false, Witherspoon, a mother-of-three, responded to the congratulatory messages with: “Thank you! I’m almost happy about it.”

The Big Little Lies star has three children, Ava, 19, Deacon, 15, and Tennessee, six. Garner also has three children, Violent, 13, Seraphina, 10, and Samuel, seven.
