But Sarah Michelle Gellar and Freddie Prinze Jr have shattered expectations, celebrating 13 years of marriage this year.

The American couple met while filming teen horror flick I Know What You Did Last Summer in 1997, but did not begin dating until 2000.

Their romance quickly escalated and by 2001 the pair were engaged, and married in Mexico in 2002 surrounded by friends and family.

They have two children, a five year old daughter and two year old son, and live in sunny Los Angeles, California.

And despite other celeb couples becoming tired of each other of being rocked by scandals, Freddie and Sarah seem to have created a lasting formula that keeps them steady.

Posting an adorable snap of her and her husband, Sarah captioned the picture: ‘Sometimes even parents need a #DateNight Up past ten pm #PartyAnimals Married almost 13 years and still enjoying each other’s company.’

Earlier in March, Sarah shared an envy inducing photo of her husband and children frolicking in the turquoise sea, enjoying the former’s birthday.

’Happy birthday to this guy @REalFPJ Thank you for showing me dreams are possible, and being the best partner a girl could ever have (esp on #InternationalWomensDay)’ Sarah wrote on Instagram.

Cutest couple ever? We think so.
