Oubre says the two began dating back in mid-2017 when he was a member of the Washington Wizards … and things were going so well, they stayed together when he was traded to Phoenix in 2018.

In fact, Oubre claims when he rented a place in Beverly Hills shortly after the deal with the Suns … he allowed her to live there with him.

But, Oubre says things took a terrible turn when the two broke things off in May … alleging 27-year-old Makena has been a nightmare.

In the lawsuit, Oubre claims she’s refused to leave his Bev Hills spot, slashed the tires on his car, stolen some of his stuff … and worst of all, taken his two beloved dogs.
