A son’s prank on his mother leads to a California nurse celebrating her supposed new status as a multimillionaire.

A Pomona, California, nursing home publicly identified one of its employees, a 62-year-old nurse, as a Powerball winner after her son told her she had the winning ticket at home, ABC reported.

A manager at the Park Avenue Health & Wellness Center had told reporters that one staffer was a lottery winner, the New York Daily News stated, with administrator David Levy saying the facility was in celebration mode on Wednesday night after receiving the news.

But the news wasn’t true; the nurse’s son had sent her a fake picture of what he claimed was her winning ticket, the Daily News reported.

The nurse’s daughter fessed up to her sibling’s prank. “It’s a joke. It’s a prank … by my brother,” she was quoted by the Daily News. “It's embarrassing. This is too much for us."

It wasn’t until she got home at the end of the day that she found out she’d been fooled, the Daily News added.

The nursing home owner, Shlomo Rechnitz, described the prank as "despicable" and told ABC News he will buy an all-expenses-paid vacation for his employee and her family.
