The 35-year-old TV host tried to pull the ultimate April Fools' Day joke on her parents when she pretended to marry her boyfriend of 15 years, Kevin Undergaro.
The "Chasing Maria Menounos" star Photoshopped a wedding photo, where she's posing with her beau in front of Chapel of the Bells in Las Vegas. Maria and Kevin are both dressed in white, and she is sporting some new bling on that finger.
Maria then got toofab's Rachel Hoffman in on the action, calling Menounos' parents for a comment about their daughter's elopement.
"Maria wouldn't do that without us," Litsa Menounos told us. "It is April Fool's Day!"
When the "Extra" host called her folks to confirm the rumors, they still didn't take the bait.
"You can't fool me, girl. That's bulls***. It's April Fools' Day!" her mother yelled. "You always ruin my jokes!" Maria said, laughing. "I can never fool you. You can't fool a Greek!"
