In a white-hot thong bikini, Kourtney Kardashian shines in the dark.

The midnight swim of Kourtney Kardashian was lighted... by her bikini, that is.

On Wednesday, the reality personality, 42, took a plunge in the dark, posting images of herself shining in a thong bikini.

“Life is merely a dream,” she captioned a series of poolside photos, her minuscule white-hot two-piece lighting up the night as she struck numerous positions on the pool deck and in the water, maybe under the influence of a black light.

Followers were mesmerized by her luminous appearance, with one calling her a "flawless mermaid" and another saying, "glowing as always."

Perhaps it's because of love that Kardashian shines: This summer, things have been heating up with her boyfriend Travis Barker, with the two regularly paddling together. 

Despite the fact that the actress wore wedding Minnie Mouse ears to Disneyland and is referred to as "stepmom" by Barker's daughter, insiders close to the pair informed Page Six that they are not engaged.

It's not the first time the Poosh creator has made headlines with her sexy photos; earlier this summer, she was hailed for releasing an unedited swimsuit shot.
