Accola, who plays high-strung vampire Caroline Forbes in the hit CW series, shared her happy news on Instagram Wednesday.
"Cheers from the future Mr.&Mrs. Joseph Aaron King," the 26-year-old wrote, posting a pic of them embracing in some gorgeous light and flashing a spectacular sparkler on her ring finger.
"Happy.... " she added with another photo of them laughing.
The Fray guitarist, 33, made sure his fans saw the announcement by also posting a close-up of his future bride and her newly adorned ring finger.
Pardon us, but that's so cheesy...
A rep for Accola also confirmed the engagement to The Times but could not provide any additional details.
The two appeared to be vacationing in Italy, taking in sights in Florence and the Banfi vineyard in the Brunello region of Tuscany. Accola has previously discussed the importance of traveling with a partner before deciding to get married, and it looks like she's sticking to her guns on this one.
The actress' newly single "Vampire Diaries" costar Nina Dobrev couldn't contain her excitement, taking to her Who Say account to share in the couple's joy and point out that she was the matchmaker.
