Brittney Griner & Fiancee -- Recruited By 'Couples Therapy' ... You Need Serious Help

The host of VH1's "Couples Therapy" says she desperately wants to get WNBA star Brittney Griner and her fiancee Glory Johnson on the show ... telling TMZ Sports they "need a hell of a lot of work."

Both Brittney and Glory were arrested last week for attacking each other in their AZ home -- and Dr. Jenn Berman says the show would be the perfect place for them to work out their issues before they tie the knot.

Dr. Berman -- a former rape and domestic violence counselor -- also says domestic violence is a serious problem in the gay and lesbian community because they tend to hide it more often.

"There's a lot of shame in the gay community when there is domestic violence because there is a kind of a sense of 'Hey, we've been fighting to be recognized as a couple and now we have this?!'"

Berman also offers the couple advice -- but says she could be most effective if Griner and Johnson agree to get her help in person ... on Season 6.
