Justin Timberlake has described fatherhood as "the most insanely amazing, wonderful, unbelievable thing to ever happen". The Grammy winner is particularly pleased because his son's first word was 'dada'.
He revealed five-month-old Silas' first word during an appearance on Jimmy Fallon's chat show. The little boy, whose mother is Justin's wife Jessica Biel, was born on 11 April. He is named after the actor's grandfather, whose middle name was Silas and his father Randall.
Jessica shouldn't be too upset because it appears that her superstar husband had been coaching Silas quite intensively using Jimmy's book Your Baby's First Word Will Be Dada. It centres around a series of pictures in which daddy animals try desperately (and utterly fail) to get their babies to say "dada" as their first word.
When the book was published in June the American comedian explained that it was "a selfish thing. I had one agenda. To get my baby to say dada".
Like Jimmy, Justin is thrilled with family life. When his wife was pregnant the 34-year-old paid her a very sweet tribute at an awards show, giving her a shout out from the podium as his "best friend and favourite collaborator".
In the first picture posted of little Silas he was wearing a sleepsuit from his father's favourite basketball team the Memphis Grizzlies. Justin's caption read: The Timberlakes are ready!!! GO GRIZZ.
The couple want to raise their baby away from the spotlight and have been spending time at their home in Big Sky, Montana. Jessica is slowly returning to work after Silas' birth - she is working on a kids' restaurant called Au Fudge.
In August, the 33-year-old also stepped out looking pretty to support her brother, also called Justin, at a launch for his accessories line in California. The night before the new mum joined her husband at a Taylor Swift concert where he joined the songstress on stage for a surprise duet, much to Jessica's delight. She stood whooping and cheering her man on from the front row.
