Kylie Jenner, 19, was the mastermind behind her pal and personal assistant Victoria Villarroel Gamero's surprise engagement on Saturday, Dec. 17.

Snapchats posted by the lip-kit mogul showed former soccer pro Marco Lobo popping the question on a hillside in Malibu, with friends and family watching from the balcony of a huge estate overhead.

The scene was super-romantic with the ground covered in white flower petals, featuring a heart outlined with candles in the center.

 

Kylie seemed pleased after finding out that she effectively "tricked" the bride-to-be in orchestrating the secret proposal.

"Congrats Victoria & Marco on your engagement I'm so happy I was able to be apart of it," she wrote next to an Instagram video. "To forever 💕💕 @victoriavillarroel 💋"

 

The "Keeping Up with the Kardashians" continued to congratulate her pal throughout the day with a slew of videos on Snapchat, including one of the huge engagement rock.

 

 

Victoria later took to social media to thank her boss and friend for all that she had done.

"@kyliejenner words can't even describe how thankful I am to have you in my LIFE," she wrote on Instagram. "I am OBSESSED WITH YOU."
