Real Housewives sure are full of surprises.
While our favorite Bravolebrities are an open book when it comes to their romantic lives today, some have tried to keep their past relationships out of the spotlight.
Perhaps it's the stress of a reunion show that brings all the confessions to the surface. Maybe it's the alcohol on Watch What Happens Live that gives these stars the courage to speak their truths.
Whatever the case may be, viewers have been surprised to learn about some past flings involving Real Housewives and other celebrities.
With recent confessions from Kim Richards and Sonja Morgan, what better time to relive some OMG-worthy couples you may have forgotten about, until now.
Sonja Morgan and Jack Nicholson
You know the toaster oven creator always keeps it real. Earlier this month, the Real Housewives of New York City star played an innocent game called "Would Morgan Date Him?" When Jack's name popped up, Sonja delivered a surprising reaction. "Have I?" she asked on Watch What Happens Live. "He's so much fun. Who hasn't? Don't forget how old I am and don't forget those days before cell phones—those old answering machines."
George Clooney and Carole Radziwill
When Brandi Glanville and Yolanda Hadid headed to the East Coast for a Real Housewives of New York City crossover episode, Carole had a confession to make about George. "We dated literally during the Eisenhower administration," she told her gal pals before describing the actor as "lovely."
Brandi Glanville and Gerard Butler
Back in January 2012, Brandi dished to Andy that Gerard was the most famous person she's ever had sex with besides her ex-husband Eddie Cibrian. She even gave Gerard an "11" when it comes to his skills under the sheets. During a radio interview with Howard Stern, Gerard later confirmed he did the deed. "It was a one-afternooner, but it was fun," he confessed. "She is wild."
Bethenny Frankel and Eric Stonestreet
In the summer of 2015, news broke that the Skinnygirl founder and Modern Family star were casually enjoying each other's company. In fact, the pair was spotted everywhere from a Los Angeles Dodgers baseball game to CAA Upfronts Celebration Party in New York City. While the relationship fizzled out, the pair remains friends.
Lizzie Rovsek and Nick Lachey
During an appearance on Watch What Happens Live, Andy Cohen brought up some talk in the building that Nick had a fling with Lizzie both before and after dating Jessica Simpson. "This is true," the Real Housewives of Orange County star confessed. "I can't lie about it anymore." And for the record, both parties have moved on and are now happily married.
