From Jay Z and Bey to Dr Dre and Eminem, this is what happens when two of the best team up.
The couple confirm the arrival of their first child.
Justin Timberlake and Jessica Biel have announced the birth of their first child.
The baby's name is Silas Randall Timberlake and representatives for the couple have said that mother and son are doing well, and that Justin is "ecstatic".
Rumours of Biel's pregnancy first surfaced last year but it wasn't until January this year that Justin confirmed that his wife was expecting their first baby together.
He made the announcement on Instagram, saying it was the "greatest gift ever". Last month Timberlake described Biel as his "best friend" and "favourite collaborator".
