Host Andy Cohen brought about the hush-hush relationship when he said that Lachey, who is now married to Vanessa Minnillo, once talked with him about Rovsek joining the Housewives cast.
"Oh my god. This woman that I used to date is about to be an Orange County Housewife," Cohen recalled Lachey saying when visiting the Bravo offices. The talk show host then asked the Sun Kitten swimsuit designer, who joined the hit reality series this past season, "You dated him both pre and post Jessica [Simpson], right?" Rovsek, who appeared to blush, admitted, "Yes."
The former pageant queen, who has remained a neutral character on season nine of the show, balancing the catfights between Tamra Judge, Heather Dubrow, and Shannon Beador, didn't fail to mention and praise her current husband, Christian, joking, "Christian's dated some hotties too."
Lachey, for his part, announced on July 15 via Twitter that he and wife Vanessa are expecting their second child together. The morning show host posted a photo of their son Camden, 2, and a heart in the sand which read, "It's a girl," with the caption, "Can't think of a better way to celebrate 3 years of marriage to my beautiful @VanessaLachey than this! #family."
