2 Celebs spotted in the crowd included English actor Daniel Portman, who plays Podrick Payne on Game of Thrones. He was cheering Ireland on from the stands

3 Rob Kearney was compared to Beyoncé in the strangest way...

Later today Rob Kearney will understand how Beyoncé feels every day when 80,000 people carefully inspect his arse #RWC2015 #IRLvITA

4 There was lots of commentary before the match even started on who is better at singing their anthem. Ireland won, obviously

Jayzus, I've heard better singers down the back at Mass than them Italian lads #IREvITA
