ZOOLANDER star Ben Stiller’s secret fling with Beverly Hills Housewife Brandi Glanville triggered the crash of his 17-year-marriage to Christine Taylor, insiders tell GLOBE!

Although the tryst came before Stiller and Christine tied the knot, sneaky Ben, 51, kept the sizzling sex secret — until he confessed on a talk show!

“It was short-lived and it was fun,” Ben told host Andy Cohen on Watch What Happens Live. “I wouldn’t characterize it as a relationship.

“It was a couple of dates and fun. I’m not sure my wife is even aware of that.”
