Golf's top player was cheering on the Irish side in their first Champions Cup, Pool 2 clash.
Rory McIlroy watched on and chatted to Rob Kearney during Leinster's 25-20 win over Wasps on Sunday evening.
His presence did nothing to help the home side in the first half as tries from Alapati Leiua and Christian Wade helped Wasps into a 20-11 half-time lead - Leinster's only scores coming from two Ian Madigan penalties and a Darragh Fanning try.
However, far better was to follow in the second half as Leinster rallied.
Fanning secured his second try of the game, while another from Dominic Ryan wrapped up all the points for Matt O'Connor's side in front of their home supporters.
