Maci Bookout's beau Taylor McKinney asked for his longtime girlfriend's hand in marriage (!) while the duo were on the West Coast with their "Teen Mom OG" cast members -- so it's only fitting that kind messages are pouring in from their MTV cohorts. One (of several) to offer her sweet well wishes: Farrah Abraham.

"After her new fiancé proposed, they came to the studios to finish our reunion taping,” Sophia's mama revealed to Us Weekly. “I stopped by their green room to congratulate them. We all hugged and embraced and congratulated Maci!”

As the mother of two told MTV News shortly after the proposal, Taylor tricked his future bride into thinking the two were doing an interview for MTV.com (sneaky, sneaky!) -- and then the lovebirds feted the occasion at a surprise engagement party with the cast and crew.

“It was very fitting and great to catch their memories for everyone to see,” Farrah dished to the magazine about the pair's milestone event. “I look forward to supporting their engagement and look forward to their wedding.”

In addition, "Teen Mom 2" familiar faces Kailyn Lowry and bride-to-be Chelsea Houska took to Twitter to congratulate Maci.
