Did Hailey Baldwin just post a message on Twitter aimed at Justin Bieber?

Someone Put Hailey Baldwin’s Private Phone Number Online!

Over the holidays, things between Baldwin and Bieber seemed to take a serious turn when the rumored couple traveled to Anguilla with Bieber's family. However, after arriving back to Los Angeles, things appear to have changed, and on Twitter, Baldwin may have just had some strong words for the pop star.

Photos: Justin Bieber Moves On From Hailey Baldwin With Selena Gomez Look-A-Like?

Baldwin traveled out of the country with Bieber just weeks ago, and during what appeared to be a romantic vacation, Bieber planted a steamy New Year's Eve kiss on the 19-year-old model, and in photos shared to both his Instagram, and her Instagram, they seemed to be an official couple.

In addition to posing with their arms wrapped around one another, Baldwin and Bieber were seen standing on the beach, and at one point, Bieber appeared to be singing to Baldwin, and playing his guitar (much like a moment he shared with Selena Gomez one month prior, in which he played the piano and sang "My Girl" to his former girlfriend).

Then, days after they returned to L.A. Bieber was spotted with another woman, Sarah Jeffery, and ever since, he and Baldwin haven't been seen together at all.
