He was over in Twickenham to witness our Grand Slam win as part of ITV's commentary team.
However, Brian O'Driscoll has been confident of the Irish rugby team getting their hands on the 6 Nations trophy for some time.
Yup, the former Irish captain made a €150 Grand Slam bet back on February 1 - being given odds of 7/2... meaning 39-year-old will get back a pretty impressive €525 in profit when he cashes in.
Unsurprisingly, a delighted BOD shared his betting slip on Instagram along with the caption: "Drinks are on me!!!"
On Friday, Brian admitted he was getting into the mood by watching back on Ireland's last Grand Slam win from 2009 - when former captain BOD himself lifted the trophy.

Brian's wife, Amy Huberman, had earlier this month marked Patrick's Day festivities by lending one of her Tweets to a good cause.
The 38-year-old actress and writer had stated on Twitter:

The suggestion prompted
Hairy Baby to ask she'd be happy to help out
Focus Ireland. The result? This classic tee:
Hairy Baby confirmed afterwards: "We've teamed up with Amy Huberman this month for a not-for-profit limited-edition chari-tee with all profits donated to
Focus Ireland to help with the great and much needed work they do."
