All four are extremely successful with their music careers, but when it came to a ‘who can blow the biggest bubble’ competition, some of these singers were left squarely on the starting line. Ever the go-getter, Katy Perry made an impressive balloon, but was less successful returning it to her mouth. Selena Gomez opted for the ‘cutesy’ bubble, which surprisingly paid off leaving her in second place. Nicki Minaj started out keen on the idea, but got distracted when she heard an onlooker accuse her of stealing Katy’s hair colour. Firmly in last place was Taylor Swift, who was overheard asking, “What is bubblegum?” Oh dear, Taylor.
