Britney Spears Includes Justin Timberlake in a Rare Throwback Photo

Britney Spears celebrated her younger sister Jamie Lynn‘s 30th birthday by sharing a throwback photo of her sibling that also happens to feature her then-boyfriend, Justin Timberlake.

In the snapshot the pop star posted to her Instagram account on Saturday of her sister from her Zoey 101 days, Spears can be seen laughing at Jamie Lynn while Timberlake is caught in the midst of saying something with his hand held over his heart.

Spears wrote in the caption, “Happy belated birthday to this beautiful soul!!! I love you so much and damn it I wish I was as smart as you at 30!!!! It’s weird to say that I was basically your momma when you were younger and yes I’m still older but your soul is and always has been wise !!!!” She continued, “I’m truly and genuinely inspired by your path and the life you have created for your beautiful children and I’m so fucking proud to call someone as beautiful inside as you my sister!!!! And not only are you a beautiful soul you’re so DAMN STRONG…I was extremely taken back and still am to this very day !!! We play wrestled at home (such classy Southern chicks) and you put me to the floor in literally two seconds after I gave all my might…I’ll never forget it!!! Maybe we should have a rematch…I mean things have changed since 6 years ago!!!!! PS I wish I was as strong as you and happy birthday!!!!”
