Katy Perry is single, having recently separated from ex-fiancé Orlando Bloom, but she has many famous exes. Perry’s past partners include ex-husband Russell Brand, singer John Mayer, and Diplo. Perry most recently sparked romantic rumors after being seen on a date with former Canadian prime minister Justin Trudeau.

Justin Trudeau added fuel to Katy Perry romance rumors on Wednesday when he was spotted at her Lifetimes Tour in Canada. The sighting comes just days after the former Canadian Prime Minister, 53, and the "Teenage Dream" singer, 40, were photographed walking in a park in Montreal on Monday, TMZ reported.

Fans spotted former prime minister Justin Trudeau enjoying fittingly prime seats to Katy Perry’s Montreal concert in photos and videos posted to social media.
