THE twists of the WNBA’s most talked about marriage took an irreconcilable turn for Brittney Griner.

The Phoenix Mercury star alleges in court documents that her pregnant wife, Glory Johnson, with whom she has filed for an annulment, cheated on her with an ex-boyfriend, perhaps the last detail to emerge in a fairytale love story gone wrong.

The powerhouse couple — Johnson is a forward for the Tulsa Shock — was engaged Aug. 14 of last year. Each was arrested for domestic violence against the other on April 22. Less than three weeks later, they were married May 8. June 5, Johnson announced she is pregnant. One day later, Griner filed papers to annul the 28-day marriage. And now, court documents show Griner alleges Johnson had been texting with an ex-boyfriend throughout their engagement, as well as having had a sexual relationship with a man while they were dating.

“Petitioner (Griner) learned that Respondent (Johnson) had been communicating with her former beau, which is documented by text messages on April 6, 2015,” the amended annulment papers, uncovered by USA Today on Thursday, say. “Petitioner was not aware that Respondent had continued admiration for her former male companion and would not have married Respondent if she had been made aware of Respondent’s continued affection for her beau.

“Additionally, Petitioner just recently learned that Respondent was not completely faithful during their courtship leading up to the engagement. Respondent intentionally concealed her sexual relations with a man to whom she was simultaneously in a relationship with from 2013 to July 2014; said relationship between Respondent and this man was unbeknown to Petitioner. Petitioner had no idea that Respondent was sexually and emotionally involved with another individual at the same time she was sexually and emotionally involved with Respondent.”

So, Griner maintains with previous knowledge of the flirty texting or the earlier cheating, she would have never agreed to the marriage (hence the annulment, instead of a divorce).

Griner amended the annulment in response to Johnson’s court documents, which asked for $20,000 a month in spousal support. Johnson is pregnant with twins via in vitro fertilisation; the unborn infants have no biological relationship with Griner.

The dissolving marriage, and alleged affair with a man, did have a shade of foreshadowing. In May, Johnson told the New York Times she is not a lesbian.

“But Brittney is different,” Johnson said. “From the beginning, I could trust her. She’s extremely caring. It was a different feel.”
