The first-time dad gushed about how much he is loving being a parent to his son Silas, who born back in April this year, and shared some adorable photos.
"It is the most insanely amazing, wonderful, unbelievable thing that can ever happen to you," Justin said, before revealing five-month-old Silas has said "dada" as his first word. How cute is that?!
Since Silas' birth, Justin and wife Jessica Biel have remained private about their life as first-time parents, sharing only a few family snaps. However Justin gave fans a glimpse of Silas with new photos that were shown on the show. One of himself and Silas, and the other of mum Jessica and Silas drying off after a bath in an elephant towel.
After the baby chat Justin reminded us all that he's probably the coolest dad ever, as he and Jimmy performed the sixth instalment of their History Of Rap!
Proving their long-time bromance is still going strong, the duo once again performed a medley of hip-hop songs which this time included 'Ignition (Remix)' by R Kelly and the Beastie Boys 'Fight For Your Right'.
