Jessica Biel and Justin Timberlake have welcomed their second child together. Justin's friend and collaborator Brian McKnight told Hollywood Life that the pair welcomed a "new baby" this summer.

While the pair has yet to publicly share the baby news, Daily Mail reported in July that the 38-year-old actress gave birth to a boy. At this time, other details—like the newborn's name, his birth date and more—are unknown.

The longtime couple are already proud parents to 5-year-old Silas Randall Timberlake.

E! News has reached out to the couple's respective reps for comment, and have yet to receive a response.

Just three months ago, Justin and Jessica celebrated Silas' 5th birthday with a heartwarming message about their "little man."

"This little man is 5 today!" the actress shared on Instagram in April, alongside a picture of her and her son. "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."

Along with the sweet message to her little nugget, Jessica revealed that she and the former *NSYNC singer were giving back in a big way.

"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 wrote. "Sending lots of love to you all."
