Justin Timberlake's Son Will Make You Want To Pinch His Wittle Cheeks

Like the gushing dad that he is, JT shares pics of Silas.

You know you have a proud parent on your hands when they cannot stop showing you pictures of their baby. Justin Timberlake is no different.

Celebrity aside, JT is one proud dad, and when he was a guest on "The Tonight Show" on Wednesday night, he was sure to dole out a lot of baby talk. Timberlake showed off pics of 5-month-old baby Silas Randall.

So cute!

“It is the most insanely amazing, most beautiful, unbelievable thing that can ever happen to you. He was 5 months [on Sept. 8]," Timberlake said about parenthood. Wife Jessica Biel gave birth to their son in April.

But it wasn't all cute and cuddly for the whole visit with Jimmy Fallon -- they also busted out another installment of "History of Rap."
