Selena Gomez and Benny Blanco are preparing to spend the rest of their lives together, and the former Disney Channel star couldn’t be happier. On December 11, the Rare Beauty founder announced that she and Blanco were engaged by sharing sweet behind-the-scenes snaps of their proposal — and according to new sources, Gomez was just as surprised as the sweet post-engagement photos suggest.

A source told People that the engagement – which took place over a picnic with her favorite Taco Bell food – left the 32-year-old ecstatic. “It was very her” said the source. The Rare Beauty founder wasn’t expecting the engagement, and the source noted, “It was a complete surprise for Selena.”

After Blanco proposed and Gomez said yes, People reported that the couple held a “spontaneous meeting” with friends and members of their respective families to share the happy news. All in all, it was a happy day for the couple, laying the foundation for their upcoming wedding. “Benny and Selena were so excited to share the news with their loved ones right away,” the source added. “It’s such a real partnership between them.”

Gomez officially announced her and Blanco’s engagement with a carousel post on Instagram, which she captioned, “Eternity begins now.” In the series of photos, she excitedly showed off her marquise-cut diamond — a nod to the line “I’m a marquise diamond/Might even make this Tiffany jealous” in her 2015 hit “Good For You” — and received a nice one Reaction from her future husband in the comments section saying, “Hey wait…that’s my wife.”
