Brazilian football fans have made a Russian flight attendant blush after they directed chanting at the cabin crew member.

The improvised onboard performance started with chants of “Polina, Polina” in support of the flight hostess, who was giving obligatory safety instructions. “Ole, ole Brazil” shouts broke out after the flight attendant put on a yellow life vest - the same color as the Brazil team.

The woman, who was visibly embarrassed by the fans' attention, continued to perform the pre-flight safety demonstration with professionalism while trying hard not to break out into laughter.
