Tom has been keeping his more than 1.29 million followers happy with regular updates on Buzz and his experience of first-time fatherhood since the tot's 14 March birth.
And there was also his sweet video, From Bump To Buzz - which shows him singing a brand new tune alongside a collage of snapshots which show HELLO! Online blogger Giovanna's belly growing throughout pregnancy.
The clip made it onto US TV and went viral, with stars such as Russell Crowe sharing it on the web.
When Giovanna found out she shared her excitement, writing: "Erm... THE Russell Crowe just tweeted a link to Bump to Buzz.......... Amazing!"
