Check out JayZ's Throwback Picture

JayZ was still a fresh boy back then shaa oo.

It is Jay Z's 45th birthday today and he is likely having a blowout celebration with friends and family.

But besides what will ensure on his special day, the rapper got a lot of love from Rihanna on Instagram.

The Pour It Up singer took to the social media app to playfully call attention to a throwback photo of a much younger version of the rapper

The 80s-looking image features the then-aspiring artist wearing gold grills and a matching thick gold chain.

With no need for a caption, Rihanna simply wrote 'Jz' alongside the upload.

Despite poking fun at the rapper, the 26-year-old owes much of her fame to Jay Z, who signed her to Def Jam Records in 2003 as then-president of the label. 

In 2007, Rihanna joined Jay Z's Roc Nation Management and they have collaborated on multiple hit songs, such as Umbrella and Run This Town.
