Rosie O'Donnell and Michelle Rounds Rosie O'Donnell had been planning an August wedding with fiancee Michelle Rounds. Instead, the pair quietly married just before Rounds underwent her first round of surgery for desmoid tumors, a rare and life-threatening condition, in June. The couple kept the nuptials secret until August, when O'Donnell shared the news on her blog, writing: "We married in private before [Michelle's] surgery, just the [two] of us. When we r both well enough will have the wedding of r dreams surrounded by those we cherish. It's been a summer of surprises for O'Donnell. She had a heart attack earlier in August and wrote on her blog that it's a "miracle" she's still alive. Janet Jackson and Rene Elizondo One of the best kept secret marriages was between Janet Jackson and songwriter and music video director Rene Elizondo. When Jackson announced in 2000 that they were splitting, she was also sharing the news for the first time that they had been secretly married -- and not just breaking up but divorcing. "I'm as surprised as you are that we managed to keep it a secret," Elizondo said at the time, of his marriage to the pop star, which lasted about eight years. Beyonce and Jay-Z Beyonce and Jay-Z are notoriously quiet about their private lives. It took Beyonce six months before she would even talk about their secret wedding to Essence magazine, saying then that people put "too much emphasis" on rings. "It's just material and it's just silly to me," she said. Of course, she was sporting a huge diamond sparkler on her ring finger after the reported April 4, 2008, nuptials. People magazine reported that the couple exchanged the top-secret vows in front of a close circle of 40 friends and family at Jay-Z's extravagant penthouse, where a white tent was erected and filled with 70,000 white orchids. Natalie Portman and Benjamin Millepied For months, Natalie Portman and Benjamin Millepied managed to fool the public about their marital status, tying the knot in August, six months after they first flaunted matching wedding rings at the Academy Awards this last February. Pictures from the August wedding were posted online. Us Weekly reported that the couple said "I do" in an intimate Jewish ceremony at a private residence in Big Sur, Calif. Portman and Millepied have a son, 1-year-old Aleph. Mark Zuckerberg and Priscilla Chan Facebook creator Mark Zuckerberg and Priscilla Chan kept their nuptials secret, instead telling guests that they were attending a surprise graduation party for Chan in May 2012. The couple wed during a backyard ceremony at their Palo Alto, Calif., home five days after Chan graduated from medical school and two days after the social networking site had the biggest tech IPO in history. The wedding was announced, of course, on Zuckerberg's Facebook page, along with a photo of the happy couple. In less than an hour nearly 200,000 people had "liked" the news. Terrence Howard and Michelle Ghent When Terrence Howard first mentioned his spouse during an interview at the Cannes Film Festival in May 2010, saying "To come here and be with my wife, it's the best feeling in the world," the world had no idea he was even married. Apparently Howard married second wife Michelle Ghent in January 2009. Unfortunately, the couple split in 2011 and had no problem spilling secrets about their nasty divorce that followed.
