It seems fourth time was the charm for Nick Viall, as he finally got engaged on Monday's season finale of The Bachelor.

While the 36-year-old businessman was proposing to his "future," Vanessa Grimaldi, his "past," Andi Dorfman and Kaitlyn Bristowe were having a girls night -- with a few other famous members of Bachelor Nation.

Dorfman, who was the first to reject Viall's proposal -- though she popped up on his season for a little heart-to-heart -- poked fun at the "historic" night in an Instagram snap.

"Say whaaaaat?!? #historical @kaitlynbristowe @whitb624 @carlywad," she wrote alongside a snap of herself hanging out with Bristowe, Whitney Bischoff and Carly Waddell.

"Name a more basic squad," she captioned the photo. "I'll wait. #historical @andi_dorfman @whitb624 @carlywad."

Jen Saviano, who was dumped by Viall on the season finale of Bachelor in Paradise after professing her love for him, posted a simple message alluding to what could've been.

"True that. Stay positive, choose wisely," she wrote alongside a message reading "You're always one decision away from a totally different life."

While Viall's relationships with his exes haven't always been sweet, the women he sent home on The Bachelor seem to have a much different impression. 

ET caught up with new Bachelorette Rachel Lindsay at the "Women Tell All" taping last month, where she said seeing Viall again was "bittersweet" -- and revealed that she "missed" the friendship that they had.
