Justin Timberlake is one proud papa.

The Grammy winner celebrated his first Father’s Day with 11-week-old son Silas Randall on Sunday.

Timberlake, who welcomed his first child with wife Jessica Biel in April, took to Instagram to document his special holiday.

“FLEXIN’ on Fathers Day,” the musician, 34, captioned the photo. “#HappyFathersDay to ALL of the Dads out there from the newest member of the Daddy Fraternity.’

The couple has largely kept their little boy out of the spotlight after introducing him on Instagram shortly after Biel delivered.

In his first social media picture, the littlest Timberlake wore a Memphis Grizzlies shirt, cheering on his dad’s home team.

The star joined a bevy of celebrities who celebrated the holiday on social media, honoring their own fathers or spouses on the special day.
