“Temptation Island” star Shanté Glover’s tumultuous relationship with Brion Whitley finally bit the dust earlier this month — but her girls had clearly been bracing for the blowup long before it hit.

TMZ caught up with Shanté’s costars Ashley Moore and Tayler Byrd — and they make it clear they tried steering her away from Brion back on the island … especially after he got real cozy with not one, but two tempters, Alex and Courtney, in that infamous threesome.

ICYMI, Shanté did go back to Brion after the show — despite all the drama — and while he tried to redeem things, even recently telling us he regretted the whole threesome mess, it clearly wasn’t enough to keep things afloat.

Despite all, the duo make it clear to us they’ve been blowing up her phone with calls and texts since she’s in a different state, making sure their girl knows she’s not going through the breakup blues alone.
