Sarah Michelle Gellar and Freddie Prinze Jr. celebrated their 13th wedding anniversary Tuesday, partly by sending each other some love Tweets.

“13 years #happyanniversary @RealFPJr ” Sarah first wrote on her Twitter account, attaching a photo of the lovebirds from their wedding. On her Instagram account, Sarah quoted poet Roy Croft: “I love you not only for what you are, but for what I am when I am with you. I love you not only for what you have made of yourself, but for what you are making of me.”

“@SarahMGellar all with minor casualties… Go us!!!” Freddie responded on Twitter, later adding, “Thx for the love today! Yay us! Hooray and all that crap. Seriously tho, thank’eth.”

Sarah and Freddie got married in 2002 in Mexico and have two kids together, Charlotte, 5, and Rocky, 2.
