US swimming legend Michael Phelps and wife Nicole celebrated their second wedding anniversary recently, and the champion athlete highlighted the day with a very sweet message for his Lady Love on Instagram.

"@mrs.nicolephelps. It's been a fast, amazing 2 years but I feel like the luckiest man in the world to have you as my best friend. You're my rock, my glue and everything that holds me together.
I love you so much and look forward to seeing what the future brings us," he wrote.
