To celebrate Mother's Day on 8 May, Justin Timberlake shared a cute photo of his one-year-old son Silas along with wife Jessica Biel on Instagram. The couple welcomed Silas Randall Timberlake in April 2015.

In the photo, the 34-year-old actress can be seen holding their son in her arms, who is sporting an adorable outfit with the phrase "I love mom" written on it. The SexyBack hit-maker captioned the photo: "M.I.L.F. Alert!!!! Happy Mother's Day to this AMAZING MOM AND WIFE. And, to all of the Mother's out there... You keep the World turning!! Hope every single one of you has an amazing day! –JT."

Fans immediately responded to the post. "That's the cutest thing I have seen today", one fan wrote, while another said: "Oh thank you for posting the picture of Jessica, she's as beautiful as always, im sure she's beautiful inside as she is on the outside! [sic]"

The 34-year-old actress also thanked her mother via the social media site. She shared the same photo and wrote: "Happy Mother's Day to you, Mom. I only, just now, understand what you did for me. And to all moms everywhere, I'm having a champagne in your honor. And when I say champagne I mean seltzer water cause mama's gotta do carpool in the am. #momlife."

The former NSYNC member had previously shared his experience of becoming a father. "Yes, having a little man in the house now changes everything!" the 35-year-old told Us magazine. "When I used to clean up my dog's poop, it was like it was a science project; I wouldn't get very close to it. When you have a kid, and there's poop, you gotta get in there!"
