Royal equestrian Zara Tindall celebrates her 44th birthday today (May 15), and while she has achieved so much, fans cannot help but obsess over her relationship with her husband, Mike Tindall, dubbing the pair a "breath of fresh air". Since marrying the former England rugby union player in 2011, fans have not been able to get enough of Zara and Mike. The couple, who have two daughters and a son together, were spotted "flirting" and dubbed "a great time" after Mike interviewed Zara on Magic Millions' YouTube page. Fans all noticed the same thing. Zara, who is part of the Royal Family, being the granddaughter of the late Queen Elizabeth II, opened up about her time being involved with Magic Millions - Australian's number one thoroughbred sales company - for over a decade, and her passion for horses. Brits were over the moon when Zara, who has previously won the World Championships and European Championships, bagged an Olympic silver medal on home turf at the London games. Zara, who loves playing polo, opened up about growing up around horses and how her mother - Princess Anne - and her father has great impact. Zara shared: "Just generally I remember being around horses when I was young and ponies and we were really lucky and my mother and father were riding so it was very much their career at the time and we would kind of do a lot of stuff at home with them, lots of quality time on the horses, and n the yard." "I think if we weren't in the house we were up in the yard, looking after them, learning about them, really lucky," she added. Zara said she also remembers having a Sheltand pony called Smokey which she revealed "the whole family used". Speaking to her husband, she added: "I just remember always loving it, the partnership, the freedom you get from it, and obviously the thrill you get from it, going fast, love jumping and being able to do it on your own. I loved looking after them and caring for animals. It was just fun." The 17th heir in line to the throne also shared that she found it difficult riding after having children. "It's just completley differnet," Zara said and expressed she found it "hard work". But she says it has been a blessing as she has been able to introduce the couple's children to the world of horses too. While fans loved hearing about her passion, they could not help point out the beautiful relationship Zara and Mike have. One observed: "Grounded, down to earth, best friends and lovers. So glad they found each other." "Loved this interview, you can see they are such a great team how they bounce off each other!," said another. "What a breath of fresh air and delightfully presented listening to such a great athlete and her beloved no1 supporter!," another commented. "Such a fun couple," said another. One other commented: "These two are a joy. She is a fabulous representative for the UK….and Mike….what can I say….flipping fab. What a partnership!"
