“Selling Sunset” star Jason Oppenheim is serious when he says his new girlfriend could end his confirmed bachelor status … at least according to costar Alanna Hall.

We caught up with Alanna while she was leaving the COSF Foundation holiday event at Balmain West Hollywood Wednesday night, where she gushed about how cute it is to watch Jason be smitten with his new love — Oppenheim realtor Jessica Vargas.

The impressive piece gained international recognition when the singer-songwriter wore it during her Christmas Holiday Special.

The necklace is made from 18K gold with dozens of diamonds running in a circle around the long loop, which once circled Mariah’s neck.
