The duo dined with two pals at a pricey steakhouse late Sunday night, then headed to a glitzy strip club before making their way to his hotel, where the pair ducked into an elevator and headed upstairs just after midnight.

Cynthia Rodriguez — A-Rod's wife and mother of their 2 1/2-year-old daughter, Natasha — was nowhere to be seen during the slugger's big night out on the town, which occurred the evening before the last-place Bronx Bombers' 7-2 loss to the Toronto Blue Jays.

And it came as Rodriguez took a room at Toronto's Four Seasons hotel — down the street from the Park Hyatt, where most, if not all of his Yankee teammates and coaches are staying during a three-game stint that ends tonight.

"No comment," Rodriguez said when The Post asked him about his north-of-the-border jaunt with the blonde.

Yankees spokesman Jason Zillo said A-Rod has "never commented on his personal or private life, and he's not going to start now."
