Sources close to the couple tell us … the HGTV star and her best husband, Joshua Hall, got married in California sometime in the last 6 months – although it is not clear exactly when. In any case … they have kept it low-key and intend to do the same at the celebrations. We were told that Christina and Josh would be hosting an intimate ceremony with close friends and family in the near future to honor their wedding – but as we said, it is legally over. We also got Christina’s real estate license, which was recently modified to reveal her new last name … now, she’s going through Christina Hall. The license also mentions some of its old legal names, including Christina Meursinge Haack and Christina Meursinge El Moussa. Surprisingly, there is no mention of Ant Anstead – her most recent ex-husband. Of course, her freshly cut husband, Josh, is a great real estate agent … somewhat perfect for overnight stays. The couple first went public last summer … and asked the question a little later, as seen in photos that have been deleted since then. Their relationship has definitely moved at a whirlwind pace – and with that in mind … it may not be so strange that they have already done the deed and become husbands and wives. Congratulations!!!
