Peter O'Mahony has taken to Instagram to share some heartwarming Grand Slam celebration snaps with his 96-year-old grandmother.
The Munster man has had an amazing week of celebrations, and even took part in the Irish squads 'invasion' of Garry Ringroses's house during the week.
While Dan Sheehan, Andrew Porter and Josh Van der Flier gave the inside scoop on what went down that evening, O'Mahony has held celebrations of his own with those nearest and dearest to him.
