Selena Gomez may be totally single, but she's a major supporter of love. In fact, the pop star threw the most romantic engagement party for her cousin, Priscilla DeLeon, where her cousin's now-fiancé, Jay Cosme, popped the question.

The Wizards of Waverly Place actress pulled out all the stops, from setting up a trail of rose petals to planning the surprise proposal just as Priscilla walked out the elevator.

Priscilla was so overwhelmed by emotion, she just wordlessly nodded her head yes.

Since Selena is also the godmother to their son, Aiden, it's pretty freaking adorable that she also planned their engagement party. Based on their Instagram hashtags, they're already planning a destination wedding in Puerto Rico in 2018. Congrats!
