It’s all ‘ad’ing up for NY fan Upton

Look who loves the Yankees! Just in time for the Yanks to take on the Astros in Game 2 of the American League Championship Series, the New York Post has taken out a half-page ad in Saturday’s Houston Chronicle, featuring this charming photo of devoted Bombers bombshell Kate Upton.

We’re hoping this Post page from the past — showing a beaming Upton wearing a Yankees cap at a home game in 2013 — will be especially appreciated by Astros pitcher Justin Verlander, who is Houston’s Game 2 starter and Upton’s fiancé.

“We know who she’s really rooting for . . .” The Post’s ad digs.

It’s signed, warmly, “From your friends at the New York Post.”

The Sports Illustrated swimsuit stunner has been dating Verlander for five years, since his days with the Detroit Tigers.

“I used to be a really big Yankees fan,” Upton admitted on “Live! with Kelly and Michael” a year into the relationship. “But I’m sleeping with the enemy.” Just not on game days, though. In February, Upton infamously admitted on Bravo’s “Watch What Happens Live” that Verlander (right) abstains before a game.

“Absolutely none,” she dished.

Here’s hoping this ad provides ovides the necessary buzzkill forr Verlander, who was traded to the Astros last month — or at least takes some of the zip off his fastball. ball.
