Brian O'Driscoll had hundreds of reasons to celebrate Ireland's Grand Slam triumph.
The former Ireland centre placed €150 at 7/2 on Ireland to do the 6 Nations clean sweep in February and their victory over England today made him €525.
A Grand Slam winner in 2009, the 39-year-old shared his betting slip on Instagram along with the caption, which included a shamrock emoji, stating : "Drinks are on me!!!”
