It's their official debut as a couple, and we couldn't be happier for her!
Shailene started dating Ben Volavola, the Fijian rugby player, in October of last year. She sparked dating rumours when she was spotted sitting on the side of his field at several of his games.
Now, the pair walk together on the red carpet for Shailene's new movie Adrift.
Could they look any cuter together? And could Shailene have a more awesome hairdo? We think not.
