Michael Bublé's New Tattoo Is So Sweet

Ever since the birth of his son in August, crooner Michael Bublé has been a smitten dad, showing off photos of the baby on his social media accounts and swooning about his growing family.

On Monday, Bublé, 38, shared a photo of his new tattoo on Instagram: "Noah," his son's name, inked on the B.C. singer's wrist. Even more adorable is the image that includes the five-month-old's chubby little fingers.

Bublé's wife, lingerie model Luisana Lopilato, gave birth to Noah, their first child, in August 2013.

Bublé told US Weekly that having Noah was "the greatest thing that could ever happen."

The singer posted the pic from Berlin, the latest stop on his "To Be Loved" tour, which comes to Canada in June.
