Keiran was with Puma before landing on Kirsten Price who was with Barrett Blade previously. try again
Danny Mountain? had a kid with Eva Angelina, then was with Angel Dark, and now is with Mia Malkova. try again
Tommy Gunn? married Rita Faltoyano, was with Cameron Dee, and now is single....try again
Devon Lee? get serious.

How about:
Manuael and Kayden?
Nikki Daniels and Jack Vegas?
Mischa Brooks and Michael Vegas?
