And the winner is . . . the jockey’s fiancée!

American Pharoah’s triumphant rider, Victor Espinoza, has won quite a reputation as a ladies man for allegedly squiring two beautiful young blondes around town at the same time — one his betrothed, the other his so-called “lucky charm.”

But it was the fiancée, beautiful Stephanie Kunkel, 25, who won a primo spot in Espinoza’s box at Belmont Saturday, a front row seat to his historic moment of glory.

His alleged “lucky charm,” 19-year-old equestrian Kelly Kovalchick, was nowhere in sight.

The Triple Crowner’s two-timing was exclusively reported in Saturday’s Post.

Kunkel’s mother, ­Julie Kunkel, insists that her daughter has been engaged to Espinoza for seven months.

But sources told Page Six’s Ian Mohr that he’s also been involved with look-alike Kovalchick, who would only say “I’m not confirming or denying anything” when asked about the apparent triangle.

The fiancée came to the track in a racy black and hot-pink dress, and bit her nails anxiously in the lead-up to the race before cheering on Espinoza into history.
