"Someone's just watched the new John Lewis advert! xxx," HELLO! Online blogger Giovanna captioned the short clip which sees Tom tell a giggling Giovanna "Every year", in reference to the annual festive adverts, which have earned a reputation for being tearjerkers.
John Lewis' latest television offering follows the story of a young boy and his penguin friend Monty.
A series of clips show the pair playing together in the run up to Christmas while singer Tom Odell's cover of John Lennon's Real Love plays in the background.
Monty and the female penguin companion he finds in the advert called Mabel both have their own Twitter accounts.
Since the campaign was released on YouTube on Thursday, Monty The Penguin's account has already garnered 16,000 followers. The advert will air on TV for the first time on Friday evening during Googlebox on Channel 4.
