The Staircase actor announced on Tuesday that he had popped the question to the model after nine years of dating. In a joint Instagram post, the engaged couple shared a series of photos from what appeared to be a beach proposal and wrote in the caption, "FOREVER AND EVER," with heart and ring emojis. In the images, the 30-year-old actor, the son of Arnold Schwarzenegger and Maria Shriver, planted a kiss on his fiancée's cheek as she showed off her double-diamond engagement ring. They also hugged and kissed near a heart-shaped floral arrangement.
