While the two have yet to officially comment on their relationship, the photos (and captions!) are quite telling. Beckham's latest Instagram post features Moretz seated in a hotel hallway with some takeout, captioned, "Late night take out with the bae."
Earlier today, Moretz shared a cute black-and-white snap of the couple snuggling in a car, with Moretz's head resting on her beau's shoulder. Beckham posted the same photo to his Instagram last week.
And Beckham practically professed his love for the Neighbors 2 star in his post on Thursday of their matching checkered sneakers. "Missing this one," he captioned the Instagram.
Of course, all this lovey-dovey back and forth started last week, with the couple's first selfie. In a mirrored snap posted April 24, Moretz looks down at the camera while Beckham casually places his arm around her.
While the teenage couple has been rumored to be dating on and off since 2014, this is the first time they've taken their relationship public. Judging by the sweet pics, one thing's for sure -- Beckham and Moretz are totally on, and we are loving it! Is it time to come up with a couple's name yet?
Moretz will star in a new live-action version of The Little Mermaid. She caused controversy when she revealed that her "modern" take on Ariel won't have red hair. Find out what else she told ET about the project in the video below.
