The stars hit headlines earlier this week when they were spotted sharing lunch in Beverly Hills, amid rumours of a new romance.
The 17-year-old and his new girlfriend left Il Pastaio hand in hand.
Peltz also alluded to a possible romance between her and the new face of Hugo Boss when she posted a sultry photo of the pair on Instagram last week. And now Anwar has followed suit.
He posted a picture of himself and Nicola, who portrayed the daughter of Mark Wahlberg's character in 2014's "Transformers: Age of Extinction", kissing.
Peltz was previously rumoured to be dating Justin Bieber back in the spring of 2016.
