Griner wrote “Last Night was a Night to Remember I became the happiest person on this earth! (almost pass out but when that one word came out I came back to life) Me and my baby @missvol25 are in it for Life!”

Baylor University alumna and Phoenix Mercury Brittney Griner proposed to her girlfriend Glory Johnson, of the Tulsa Shock, this weekend.

The couple posted photos of their engagement on their Instagram accounts.

Griner, who is from Houston and played basketball at Baylor, came out in an interview with SI.com, Sports Illustrated’s website, in 2013. She published In My Skin: My Life on and off the Basketball Court, a memoir, earlier this year, detailing her struggles growing up and remaining in the closet as a lesbian.

According to the Washington Post, “Griner was not to come out publicly because university officials, including [coach Kim] Mulkey, worried it would hurt recruiting. She lived in what many call a “glass closet;” she would bring her college girlfriend to events, but elsewhere, both online and offline, Griner was expected to live under a cloak of ambiguity.”

The couple have been together since June.
