Now he faces up to a year on Rikers Island — which is not La Isla Bonita.

Madonna-besotted former city firefighter Robert Linhart was convicted yesterday of resisting arrest after flailing his arms as he was busted painting love notes on giant wooden boards outside the star’s Central Park West building.

“Madonna I need you,” read one. “Tell me yes or no,” read another. “If it’s yes, my dream will come true. If it’s no, I will go. XXX.”

Linhart had every right to paint his signs peaceably, but not the right to resist arrest, jurors said.
