Of all the royal couples, Zara Tindall and her husband, former rugby star Mike, have the crown for public displays of affection. The 45-year-old has been married to Princess Anne's daughter since 2011 and claims he gets on with her extended family because he's always been 'nice to them'. Celebrating her 44th birthday, fans got a glimpse of her husband's 'mushy side' as he posted a message online. He shared a fab picture of them, with Zara wearing a beautiful long purple dress and them gazing lovingly into each others eyes. Mike kept the message short and sweet, with a cheeky twist that many women might be able to relate to! He penned: 'Happy Birthday to the better Tindall. She's even let me play golf on her birthday!' Now, for many men out there, getting a chance to hit the golf course, particularly on your wife's birthday, can be a touchy subject, but for Zara, it was no problem... if that isn't true love, we don't know what is! In his stories, Mike gave his followers an idea of how the day was going with a shot of him standing by some refreshments with his golf stick in hand. With Mike heading out with the boys for the day, we're sure that he will have something special planned for her birthday in the evening.
