Jeter opens up on fave undies, while Melo’s rep pulls block

Derek Jeter let us in on what’s going on below his belt at Thursday’s opening of Frigo’s pop-up store in the Meatpacking District.

The Yankee slugger is a fan of the brand’s RevolutionWear undies, which run $100 a pop and feature an inside pouch that can be adjusted for, ahem, a customized fit.

But don’t expect Jeter to appear in an ad in his high-tech, high-priced pantaloons — dubbed by some as the “TempurPedic banana hammock” — anytime soon. “It’d be too embarrassing,” he told us, noting he is pals with the brand’s Mathias Ingvarsson.

Off the field, Jeter has a new imprint for Simon & Schuster, Jeter Publishing. “I am interested in people’s stories,” he told us. “I like to read about success stories but, more importantly, when the end result is success, the failures leading up to it. I think a lot of times people see success stories and people automatically assume they started there. I like to see the whole process.”

While the shortstop couldn’t have been more professional and friendly, even suggesting we check out his current reading material, an ­Andre Agassi biography, Carmelo Anthony was ducking all questions.

Anthony’s rep, PMK’s Michael Geiser, pulled off an aggressive block and wouldn’t let anyone near the Knick star and his wife, La La.

When we asked grumpy Geiser if he was Melo’s rep, he blatantly lied, curtly telling us, “No.” On our third attempt to speak to Geiser, he put his hand up, turned and ushered his clients in the door, fiercely protecting the delicate 6-foot-8 baller from Page Six’s petite 5-foot reporter.

When a rep from another p.r. firm tried to help us, Kommandant Geiser shut him down. Back in the office Friday, Geiser conveniently told us he didn’t remember the incident and denied even seeing a Page Six reporter at the store.

He explained he had only been trying to figure out how to get Anthony into the event and offered his apologies. Others said Geiser’s behavior wasn’t like him at all. Hey, we all have our bad days.
