Starbucks and Ariana Grande sparked confusion on Monday with mysterious twin tweets. 

Both the singer and the coffee chain tweeted a similar combination of emojis around noon ET on Monday. Grande additionally retweeted Starbucks' tweet.  

The tweets sent Grande's fans into a frenzy on Twitter. 

According to internal documents viewed by Business Insider, the collaboration will result in a new drink launching on Tuesday, plus a Starbucks playlist featuring Grande's music. Starbucks declined to comment when contacted by Business Insider on Monday.

The new drink seems to be the Cloud Macchiato, according to internal Starbucks documents. The espresso-based drink features cold whipped foam and a caramel drizzle. Grande's love for clouds (and the cloud emoji) is well documented, with the singer launching a Cloud perfume in February.
