Who knew Hugh Jackman was a KatyCat? The actor took to Instagram on Tuesday to share a hilarious Dubsmash video of himself lip-syncing to Katy Perry's hit "Teenage Dream." Hugh, who appears to be in a car during his solo karaoke session, captioned the clip, "Oh nothing much . . . just singing along to @katyperry! Living a teenage dream!!"
