After beating out Jimmy Fallon with a big opening night, veiwership for Stephen Colbert’s second installment of the “Late Show” dipped to 3.7 million. Timberlake also showed a third picture of him watching television with his son.

Justin Timberlake, 34, has really adjusted nicely to fatherhood.

The A-lister said: ‘It is the most insanely fantastic, wonderful, unbelievable thing to ever happen to you’.

Justin Timberlake unveiled his son Silas Randall Timberlake in a big way on the Tonight Show with Jimmy Fallon.

The Yogi Bear star gushed about how much he is loving being a parent for the first time to his son Silas, who was only born back in April.

The bit, where Fallon and Timberlake sing – in rapid succession – a medley of rap songs, is one of the most popular in late night TV.

While we couldn’t quite see who Silas looked like when Jessica Biel first showed off their baby, now it’s clear that Silas takes after his mother.

And he even showed one of his attractive wife sharing a kiss with their baby as they dried off after a bath. His comedic talents are being totally wasted on all that new music we’re still waiting for. Or to just join Jimmy Fallon’s show permanently?

With Federer looking invincible against Richard Gasquet, Fallon and Timberlake were spotted by ESPN’s camera crew at the same moment Beyonce’s Single Ladies hit blasted through the centre court speakers. They have shared several photos of Silas, now 5 months old, since his birth, but none have been cuter than the latest batch.

In a rivalry stretching back seven years, the two men have met four times at the Grand Slams but just once at the US Open when Djokovic won in four sets in 2008.
