Michael Phelps shares first picture of his secret wedding Sunday Oct 30,2016

Michael Phelps has shared the first photo of his wedding to Nicole Johnson after it was revealed that the couple married this summer but kept it secret for months.

The Olympic legend posted the picture on Instagram on Sunday Oct 30,2016, captioned: 'My best friend.... I love you!!'

It shows a grinning Phelps looking dapper in a light-colored suit as he walks hand in hand down the aisle with his bride after tying the knot.

Phelps didn't reveal details, but the image shows they had an outdoor ceremony and that Johnson looked radiant in a dress with an intricately embroidered bodice and thigh-high slit in the skirt.

And the couple's baby son Boomer, just a few weeks old at the time of the wedding, can be seen behind Johnson in the arms of a bridesmaid.
