Mike Tindall | Zara and Mike Tindall ‘madly in love’

Zara and Mike Tindall are still “madly in love”.

The couple tied the knot in Edinburgh on July 30, 2011, and after 13 years of marriage, their relationship is only getting stronger.

Former BBC royal correspondent Jennie Bond told OK magazine: “They seem to get better and better as the years go by. It’s great to see a couple who are still clearly in love with each other and act like newlyweds when they’re out and about. They’re the most tactile of all the young royals and also the most fun, which makes them immensely likeable.”

Jennie went on to praise Olympic equestrian athlete Zara, 43, and former rugby star Mike, 45, for being so “down to earth”.

She said: “I’ve never met anyone who had anything bad to say about the Tindalls. They are an incredibly charismatic couple and the fact that they have remained so down to earth despite their royal status has endeared them to the public.”

Zara – who is the daughter of King Charles’ sister Princess Anne and her ex-husband Captain Mark Phillips – met Mike in a bar in Sydney, Australia, during England’s 2003 Rugby World Cup campaign.

Relationship Nicky Wake said: “Although they keep a low profile, they are known for their affectionate and playful interactions – which is charming to the public. They have plenty of date nights, which will help keep the spark alive and remind them why they love each other.”
