The Hollywood couple - who married in 2002 - usually keep their relationship away from the cameras, but made an exception on Wednesday (12 March) to mark Sarah reaching 200,000 followers on Twitter.
Alongside the cute image, Sarah wrote: "Now only because this is a special occasion.... To all my fans, for your loyalty and support, I thank you. 200,000!!!"
Buffy The Vampire Slayer star Sarah had promised fans she had "something special" in store once she hit the magic number and she certainly didn't disappoint!
She only joined Twitter in October 2013.
Sarah and Freddie met on the set of hit horror movie I Know What You Did Last Summer back in 1997. (We know, makes us feel old too.)
They became engaged four years later and married in Mexico in 2002, treating guests to a four-day extravaganza in the sunshine. At the time, Sarah told People: "We are each other's best friend. He is my first love."
Sarah and Freddie are parents to daughter Charlotte, born in 2009, and son Rocky, born in 2012.
