PERRY’S GOT A ‘FRIEND’ IN JENNIFER

US OPEN NOTEBOOK

MATTHEW PERRY, waiting out the rain in Flushing to see his pal Jennifer Capriati in action, is a frustrated tennis-player wannabe.

While the “Friends” star loves attending the Open to watch the matches, “mostly, I just sit around the players’ lounge and pretend I’m a pro,” he quipped.

Andre Agassi has a weird way of warming up for the U.S. Open every morning.

“Well, I start by changing some diapers, followed by, you know, cooking some breakfast for a 2-year-old, followed by a little bit of Buzz Lightyear,” he told the San Diego Union Tribune.

When it’s court time, Agassi, 33, turns the kiddie-care duties over to wife Steffi Graf.

Another scalper has been scalped by the cops. Yesterday, The Post did an interview with the ticket scalper wearing Phat Farm duds and shiny designer watch who bragged of raking in thousands of dollars at the Open.

“There are a thousand undercover cops out here. They want the overtime,” he said cockily.

Minutes later, it turns out, police busted him

The crowds at the U.S. Open still can’t get over the fact that the NYPD dogs that patrol the stadium wear photo IDs, just like their masters.

Detective William Popper, who takes care of a 4-year-old black Labrador named Peyton, said it appears the dogs sometimes wonder about it, too.

Popper said Peyton was “looking at me, like, ‘What do you want me to do here?’ when the pooch posed to get its photo taken.”
