Rosie O’Donnell has opened up about her friend Whitney Houston’s sexuality.

During an appearance on Watch What Happens Live With Andy Cohen, the comedian addressed rumours that Whitney was in a romantic relationship with her longtime assistant Robyn Crawford.

“I didn’t know them as a couple per se, but I knew that they were together,” she said.

“I’m friends with a lot of very athletic, older lesbian women who are in the WNBA. And that’s sort of the group [they hung out with], all of these basketball-playing women. So I knew that, and I knew it for a very long time.”

It’s long been speculated that Whitney was in a relationship with her assistant Robyn, but further fuel was added to the fire when the critically-acclaimed documentary Whitney: Can I Be Me? was released earlier this year.

In the film, a number of Whitney’s friends and family members suggest her relationship with Robyn was more than just platonic friendship, a claim which is backed up by Rosie.

“Everyone sort of knew it,” she continued, “so I thought it was very surprising when Clive Davis came out and said that he never discussed her being gay. I don’t believe that for a minute.”
