PHOTO: Eugenie Bouchard's selfie with Pope Francis

It appears the selfie phenomenon has taken hold, for better or worse - but it will be hard to top the self-portrait Canadian tennis star Eugenie Bouchard shared via Twitter on Wednesday:

That's Bouchard with the ultimate photo-bomb - snapping herself in the foreground as Pope Francis' motorcade rolls past.

The 20-year-old is seeing the sights after being bounced by local star Francesca Schiavone in straight sets in opening-round action at the Italian Open in Rome on Monday.
