Lizzie Grubman got a big surprise yesterday when The Post marked her 31st birthday by giving her a cake.
“Oooh! This is soooo sweet!” cooed the blond p.r. princess outside her Midtown apartment building.
For a few moments, she couldn’t take her eyes off the tasty chocolate confection, which featured the infamous “Lizziemobile” in white frosting.
“Who sent it?” she asked.
When a Post reporter told her the cake was courtesy of New York’s favorite newspaper, Lizzie beamed an ear-to-ear grin.
“Thank you!” she roared.
Then she grabbed the cake, gingerly stepped into her waiting SUV and was whisked away to her public-relations office by a private chauffeur.
Lizzie’s birthday surprise was one of the few happy moments she’s had since mowing down 16 people with her SUV in the Hamptons last summer.
It was a welcome relief from the barrage of publicity over her upcoming trial, in which she faces assault and drunken-driving charges that could send her to the slammer.
