“This little man is 5 today!” Biel wrote alongside an adorable photo with Silas hanging off his smiling mom’s shoulder. “We’re at home, covered in legos and birthday cake right now… but I just found this pic on my phone from last summer and it made me so happy.”
“To celebrate his big birthday, we’re supporting @savethechildren and @feedingamerica, who are doing so much good work to keep kids and families healthy and fed during this time,” she continued. “Scroll through your old pictures today and post something that brings you a little bit of joy! Sending lots of love to you all…”
Timberlake shared the post to his Instagram story with the caption, “Our dude is 5!!” and mind-blown emoji.
