Princess Madeleine of Sweden shares wedding photo on two-year anniversary

June is shaping up to be an especially exciting month for Princess Madeleine of Sweden. The heavily pregnant royal is due to welcome her second baby with husband Chris O'Neill any day now, and on Monday the couple also celebrated their two-year wedding anniversary.

Taking to Facebook to mark the special occasion, Madeleine posted a sweet throwback photo of herself and Chris gazing into each other's eyes.

"Today we celebrate 2 wonderful years as a married couple and we are excited for what the future will bring us!" Madeleine, who already has one daughter Princess Leonore, fittingly captioned the snap.

Today we celebrate 2 wonderful years as a married couple and we are excited for what the future will bring us!

Princess Madeleine of Sweden married Chris O'Neill on 8 June 2013

The beautiful royal was the epitome of a fairytale bride on her June wedding day back in 2013, when she wore a breath-taking bespoke Valentino gown. Italian designer Valentino Garavani had stepped out of retirement specifically to create Madeleine's dress, an act he called "an honour" for a "beautiful" bride.

Both the princess and the fashion maestro were thrilled with the final result – a pleated silk organza gown with appliquéd Chantilly lace that showed off Madeleine's enviable figure.

Leonore, our little sunshine turns 1 year old today!

The couple, who are expecting their second baby, are already parents to daughter Princess Leonore

Months have passed since that sunny day in Stockholm, and Madeleine and Chris are now expecting their second baby. When the little prince or princess arrives, as the couple have not revealed the gender of their baby, the couple will be looking after two children under the age of two, much like their English counterparts Prince William and Kate.

Madeleine's most recent appearance took place over the weekend, when she stepped out to celebrate Sweden's National Day with her family.

She has been temporarily residing in Stockholm – the city where she plans to give birth – for the past few months, having recently moved from New York where Chris worked as a businessman and a banker.

This weekend I saw my brother race. Proud and happy that he supports Childhood!

It is not yet known whether Princess Madeleine (pictured last year) will attend her brother's wedding, as she is due to give birth any day now

When the lovebirds and their daughter become a family of four, Madeleine plans to move her brood to London in the autumn. The 32-year-old lived in the capital when she was a teenager and is said to have loved it because she could be "anonymous".

The move would also make sense for Chris, as he often travels to London for business.

Because of the princess' imminent due date, it is not yet known whether Madeleine will attend the wedding of her older brother Carl Philip. The prince is set to marry his model fiancée Sofia Hellqvist on Saturday 13 June in the palace's royal chapel.
