Over the week, Nadine Lustre surprised fans when she wore a black two-piece bikini at her post-summer vacation in Cebu.
But the fans' eyes turn heart-shaped when they realized Nadine and James Reid's sister, Lauren Reid, sported matchy-matchy black bikinis.
Since tagging along with JaDine in their North American concert tours, Lauren and Nadine have become social media's new favorite BFFs.
These two beauties previously sported similar black-on-black ensembles.
On top of that, they pop up on each other's Snapchat accounts!
Lauren has been one hundred percent supportive of her newfound sister's projects, too.
So, PEPsters, what can you say about LauDine?
