Former Canadian Prime Minster Justin Trudeau showed subtle support for girlfriend Katy Perry’s new single, ‘Bandaids,’ by posting a photo sporting a bandage on his arm after getting a flu shot. The single seems to address Katy’s decision to call off her years-long engagement to Orlando Bloom earlier this year, with references to how a past romance was metaphorically killing her. She and Orlando remain in each other’s lives, though, as co-parents to their 5-year-old daughter, Daisy.
