Mariska Hargitay shared a throwback snap of her wedding night with husband Peter Hermann, on the couple's 19th anniversary.

The 59-year-old actress - who put on the 4th Annual Joyful Heart Walk for her Joyful Heart Foundation earlier this month - shared a snap of her first dance with her 56-year-old husband from their wedding on August 28, 2004.

'19 years. Best dance of my life. Only dance of my life,' Hargitay captioned the snap, while tagging photographer Lara Porzak.

Hermann was cast in a recurring role as defense attorney Trevor Langan in 2002, with the couple tying the knot two years later.
