But they're also good friends in real life, so when Cuoco married professional equestrian Karl Cook on Saturday, Galecki was on hand to wish his "fake wife" some kind thoughts and even shed a few tears. Galecki posted a sweet photo of himself holding the bride's hands at the wedding, noting that Cook's words had gotten him emotional: He also added this amusing shot of himself posing with the couple ... with Cuoco pretty much cut out of the picture! Leonard (Galecki) and Penny (Cuoco) married on "Big Bang" in 2016, but their connection doesn't stop there — they were a real-life couple from around 2007-09 as well, though they kept that relationship secret. On "The Big Bang Theory," Penny (Kaley Cuoco) married Leonard (Johnny Galecki) and in real life, the pair were a couple for a time. Getty Images In 2010 Cuoco said, "It was such a huge part of my life and no one knew about it. It was a wonderful relationship, but we never spoke a word about it and never went anywhere together." Fortunately, after that breakup the pair remained pals. "I'm so lucky it was a mutual ending and that we don't hate each other," she said. "We dodged a huge bullet. Dodged a war." And today all is peaceful and happy! Follow Randee Dawn on Twitter.<doc-sep>As Kaley Cuoco writes on Instagram, the actress is "legally KCSQUARED." In other words, she and Karl Cook are officially married. The "Big Bang Theory" star and her equestrian husband tied the knot on Saturday, seven months after their engagement. The two horse lovers (Cuoco is a rider and jumper, too) had been dating for almost two years before Cook popped the question on Cuoco's 32nd birthday. The actress wore a custom Reem Acra lace beaded gown and matching cape by Reem Acra with her hair in a loose bun for the nuptials, then changed in to a ponytail and showed off a Tadashi Shoji lace jumpsuit at the reception. "Ok let’s party!!!" she wrote on Instagram. Cuoco was previously married to tennis player Ryan Sweeting. They wed on New Year's Eve 2013 and split 21 months later. “I honestly thought I wouldn’t get married again. My ex ruined that word for me," Cuoco said in an April interview with "Cosmopolitan." "I knew how much I had to give and how much I wanted to receive (after my first marriage). I knew I just had to be patient. … I had to go through a lot of things, but it brought me to Karl.” On Sunday, Cuoco shared a photo of herself and her new husband in matching denim jackets that said, "KC squared... Together Forever." Johnny Galecki, Cuoco's on-screen spouse and one-time offscreen boyfriend, posted a sweet photo of the two of them at the wedding reception, writing, "I couldn't be happier for my fake wife." Congratulations to the couple!<doc-sep>
On June 30, actress Kaley Cuoco tied the knot with equestrian Karl Cook in a ceremony that took place at a horse stable near San Diego. The day seemed like an absolute fairytale, as the couple delivered their own vows surrounded by friends and family, with Cuoco’s sister, Briana, actually officiating the nuptials. The night of the wedding, Cuoco’s “The Big Bang Theory” co-star Johnny Galecki took to Instagram to congratulate his friend on her big day. Alongside a photo of the two friends holding hands at the event, Galecki wrote, “Couldn’t be happier for my fake wife [Cuoco] and [Cook] whose words brought all to tears last night. So much love for you both.” https://www.instagram.com/p/BktBDbiB8EC/?utm_source=ig_embed In addition to their working relationship portraying married couple Penny and Leonard on “The Big Bang Theory,” it’s clear from Galecki’s moving message and the huge smiles on their faces in the photo that these two have a great friendship as well. The pair even once secretly dated, but were apparently able to keep things friendly after that ended. “He’s one of my best friends and one of the closest people I’ve ever worked with,” Cuoco said of her former flame during a 2017 appearance on “The Talk.” Getty Images | Matt Winkelmeyer How sweet! We’re so glad that these two were able to maintain such a wonderful professional and personal bond even after they didn’t work out as a couple. Galecki was not the only “Big Bang Theory” actor at this star-studded affair.
