Her Tv co-star Nina Dobrev, who recently split from longtime boyfriend and castmate Ian Somerhalder, was quick to send her congratulations, writing on her Twitter.com page, "Dying right now! So excited/thrilled/happy/hyperventilating over your engagement! Match made in heaven!"
She later joked, "What colors are we thinking for the bridesmaids dresses? Because yellow isn't a good color on me."
