The SURvers can't stop gushing about their co-stars' exciting moment.

Tom Schwartz finally decided it was time to tie the knot and proposed to longtime love Katie Maloney with some serious jewelry. The couple's Vanderpump Rules co-stars took to social media to express their delight about the upcoming nuptials.

Scheana Marie was over the moon for the two — and also took the opportunity to show off her own bling alongside her bestie.

Jax Taylor was thrilled for his best friend and his lady, expressing how happy he is to be a part of their lives (and probably a part of their wedding!).

Ariana Madix summed it up perfectly in just one word: "Perfection."
