A pregnant woman in Australia put her baby daddy on blast by spray-painting messages for him in public spaces in a desperate plea that’s since gone viral.

The unidentified vandal scrawled the all-caps messages in purple paint all over the Melbourne suburb of Frankston — catching the eye of a local Facebook page administrator.

“CHRIS U NEED 2 TALK 2 ME BEFORE BABY IS BORN OR DONT BOTHER AFTER,” they read, according to photos posted to the Frankston Community Noticeboard.

The same message appeared on brick walls, doors, the pavement and garbage dispensers throughout the neighborhood.

“Chris… Can you please just call her before she destroys the whole city?” the local page posted Monday. “Don’t forget if you see graffiti, you can report it to council via [the app] Snap Send Solve.”

The photos were shared more than 10,000 times in less than a day, and comments soared to more than 24,000.

But they apparently weren’t enough to capture Chris’ attention before the Frankston City Council had the graffiti removed — thanks to residents reporting it through the app, the Australian Broadcasting Corporation reported.

“Council acted quickly to remove the graffiti from affected areas, and would encourage those involved to consider more constructive, and less illegal ways of communicating in the future,” Frankston Mayor Michael O’Reilly told the outlet.

One of the admins of the page, who did not want to be identified, said he created the “tongue-in-cheek post” because he was “pissed off.”

“Frankston works really hard to have a good reputation and it’s annoying when this happens,” the admin said.

Meanwhile, O’Reilly urged the public to share any tips with police.

“I hope Chris and this mystery person can work through their issues,” he told the outlet, “and in the future, refrain from undertaking illegal activity that bear a cost to [taxpayers].”
