Selena Gomez just may be the best maid of honor… well, ever. The “Wolves” singer, who holds the coveted position in her cousin, Priscilla DeLeon’s upcoming wedding, just showed up to the bride’s dress fitting with a MAJOR surprise — her dream wedding gown!

The bride-to-be showed off her special moment with her family member with a video posted to Instagram, writing, “When your maid of honor makes your dream dress a reality and surprises you with it!”

In the short clip, DeLeon can be seen grinning and holding up a sign which reads, “I said yes to the dress!” as Gomez, 25, snuggles up at her side.

The girls toasted the event with a glass of champagne, drank (or mock drank) straight from the bottle by the pop star.

According to Teen Vogue, the singer, who is also the Godmother to DeLeon’s son, has been helping her family member to celebrate for quite some time now, posting a shot of the girls celebrating her engagement as far back as 21 months ago.

“We have waited our whole lives for this,” she wrote on a shot of herself hugging her teary-eyed cousin, along with the hashtag, “#whyamIactinglikeIgotaring.”

Maybe, just maybe, she’ll get her own from BF Justin Bieber someday? In the meantime, we can’t wait to see the sure-to-be-gorgeous gown she gifted Priscilla with.

Congratulations, Ms. DeLeon!
