Baldwin and Bieber were last seen together last Friday, intensely making out on the streets of New York City. The two didn't seem shy about packing on the PDA, with the 24-year-old pop star at one point grabbing Baldwin's backside as an onlooker snapped their pic.
The rumored pair briefly dated in 2015 and have seemingly rekindled their romance in recent weeks, enjoying dinner dates in the Big Apple and outings in Miami. Hear more (and see pics!) in the video below.
