Rugby legend Brian O'Driscoll and his wife Amy Huberman welcomed the arrival of their new baby boy Billy last month, and naturally people across the country offered up their congratulations.

But one young man called Adam went a step further and sent a card to Brian along with a €2 coin taped on the inside for Billy. Of course, BOD tweeted his thanks to #generousAdam:

Firstly there was a couple of bob for our little one & now the wee man getting a few quid. #generousAdam pic.twitter.com/Cmj97Xu5rg

And it looks like this wasn’t the first time Adam shared his pocket money with the young O’Driscolls – he begged Brian to stop having babies as he "will have my bank account cleared out”.

Here’s the note in full:

To Brian, Amy + Sadie, Congratulation on your new baby boy Billy. Hope he is not too noisy

P.S please stop having babys you will have my bank account cleared out

love Adam

Bless.
