Justin Timberlake shared the first photo of his baby boy, Silas, with Jessica Biel, his wife, on Instagram on Sunday night.

"The Timberlakes are ready!!!" the pop star captioned the photo, adding "GO GRIZZ!" in support of the Memphis Grizzlies in their Sunday night game against the Portland Trailblazers. Along with baby Silas' Memphis Grizzlies T-shirt, it seems that the little one is already taking after his father's taste in sports allegiances.

The Timberlakes welcomed baby Silas Randall Timberlake a little more than a week ago, so this appears to be the first photo of the handsome baby.

The couple similarly confirmed their much-rumored pregnancy in a social media photo earlier this year, which Timberlake posted to coincide with his 34th birthday.
