The 26-year-old actor proposed with a pink and gold diamond ring. The actress has since been spotted wearing the accessory. After the big engagement, the couple reportedly spent New Year's Eve together in London.
Celebrity photographer and friend to the couple, Tyler Shields, sent a congratulatory message to the couple via Instagram, posting: "Congrats to @emmaroberts6 on her engagement love you! It's important to marry someone who is there to catch you when you fall..."
Back in July 2012, Roberts was arrested (and quickly released) after police responded to a domestic dispute between the actress and Peters. Prosecutors later dropped the charges. "It was an unfortunate incident and misunderstanding," the actress' rep told ET. "Ms. Roberts was released after questioning and the couple are working together to move past it."
