On Dec. 13, McDonald’s embraced the power of influencer marketing with an impromptu promotion sparked by none other than one of the most famous songstresses of the holiday season, Mariah Carey.

In a tweet, McDonald’s offered to give free Big Macs to customers if Mariah Carey retweeted that same McDonald’s post. The 10-word tweet — one reading “if @mariahcarey retweets this everyone gets a free Big Mac,” resulted in a flurry of excitement on social media (and a special one-day-only deal) when @MariahCarey did, in fact, retweet it.

McDonald’s followed up with details relating to the offer, which gives app users a free Big Mac with any purchase of $1 or more (excluding tax) at participating locations. The free Big Mac offer launches the first of McDonald’s’ 12 days of free menu items, adding a bit of holiday magic to the season.
