STILL HUNG UP ON EX KALEY!

Johnny Galecki has been blushing up a storm after his ex – and The Big Bang Theory co-star – Kaley Cuoco gushed about their romance in a recent interview.

According to a source, Johnny is still smitten with Kaley, who announced her divorce from second husband Karl Cook in September. They dated on the down-low between 2008-2010.

“Johnny never got over her. None of the women he’s dated has managed to outshine Kaley, but even more worrying is he’s convinced she keeps divorcing these guys because he’s The One,” claims the source. “Her carrying on about the good old days with Johnny is going to mess him right up and make it impossible to ever move on.”
