Mother's Day saw another interesting twist in the Derek Fisher, Gloria Govan and Matt Barnes love triangle.

The former Knicks coach posted a picture of the "Basketball Wives: L.A." star on his Instagram in a photo that depicted her with the sons she shares with Barnes. It's likely yet another move that will upset the Grizzlies role player, who can't stand Fisher, his ex-teammate, being with his ex-wife.

It's hard to fathom any scenario where Barnes wouldn't take exception to Fisher posting photos of his ex-wife and two sons on social media.

Barnes posted a tribute to Govan -- another picture with her and their sons -- on Instagram, but hasn't publicly reacted to Fisher's social media move.

The two former teammates have already had a physical altercation as they got into a fight back in October at Govan's house. After he learned of Fisher's romantic involvement with his wife, Govan crashed a party and struck him.

Barnes also reveled in Fisher's firing from the Knicks back in February, posting a picture of himself in a suit in a move that was seen as the NBA star trolling his former teammate. He also commented on a UFC simulation video that was posted and depicted Barnes beating up Fisher in the Octagon.

"My kids showed me that," Barnes told TMZ Sports. "That's what would really happen if it came down to it. I'll do it to him anywhere, boss."

Fisher and Barnes' ex-wife were keeping their relationship secretive at first as Govan deleted a photo showing her and a group of people -- including the former Knicks coach -- getting ready to board a plane to celebrate her 30th birthday party back in February.

All of the mystery came to an end when Fisher and Govan were seen publicly kissing and enjoying piggy back rides in Los Angeles in March, according to the New York Post.

Barnes, who recently posted a meme knocking Fisher after the D'Angelo Russell-Nick Young incident involving "Swaggy P's" fiancée Iggy Azalea, has made no secret of the fact that she wants to fight Fisher again.

"I know I got to keep my mouth shut because then he'll run and tell," Barnes said about Fisher in January during the lead up to a Grizzlies-Knicks game via The New York Daily News prior to Fisher's firing. "So we're focused on playing that team [the Knicks]. And when I'm retired, him and I will cross paths again."
