Justin Timberlake is a many juggling many hats at the moment. He's an international pop sensation, a co-owner of the Memphis Grizzlies, and a proud new papa, too.

Timberlake and his wife, actress Jessica Biel, recently welcomed a baby boy named Silas into this world, and the couple's fans have been waiting to see a glimpse of him via social media. Timberlake granted that wish on Sunday, posting a photo to Instagram of Biel cradling the young Silas. And Silas, appropriately, looked adorable decked out in Grizzlies gear. A baby bear cub, if you will.

"The Timberlakes are ready!!! GO GRIZZ! #GritNGrind #Playoffs #BabyGrizzROAR," the "Suit & Tie" singer said.

Timberlake's clearly excited about the new role fatherhood has bestowed on him. "Justin is so excited, he doesn't know what to do with himself!" a source told US Weekly recently.

The Grizzlies themselves, for what it's worth, heard Timberlake's cheers. They defeated the visiting Portland Trail Blazers to take game one of their opening round playoff series on Sunday evening.
