When we first posted the news that Toronto Raptors shooting guard Lou Williams was in an open relationship with two different women, we had no idea if that arrangement was built to last.

Well, months later, it looks like the trio is still going strong.

The 28-year-old NBA player is reportedly in an open relationship with two women at the same time, Ashley Henderson and Rece Mitchell. Williams has affectionately nicknamed one of them Blonde and the other Brown -- clearly based off the color of their hair -- and routinely posts pictures to Instagram of himself and the lovely ladies.

Williams also has a child with Henderson.

Mitchell's birthday was this week, and the unorthodox couple let their followers know on Instagram that they were partying it up. All indications are that the three are still going strong.

“Perfect piece to the puzzle! You don’t understand and you never will but this fam right here nothing but love happy birthday babe @rece_gorgeous,” wrote Henderson to her "sister wife."

Mitchell meanwhile posted a photo of herself and Sweet Lou, captioned "I can't imagine my life without him ... Love you @louwillville."
