Apparently, Megan Mullally had no idea Ellen DeGeneres’ roommates were her girlfriends.

Will & Grace star Megan Mullally and Ellen DeGeneres have been friends for 30 long years.

While you might think three decades is enough time to learn everything there is to know about someone, these two proved that people are always filled with surprises.

Appearing on the Ellen DeGeneres show, Mullally revealed that she naively thought that DeGeneres just had “lots of lovely roommates”, and would often come to visit from her house the street over in Los Angeles.

“I remember thinking, ‘Oh, that’s nice, Ellen has this lovely roommate … they really seem like they get along great,’ And then, as the years went on, [she] had a lot of really lovely roommates, and I thought, ‘Ellen just gets along so well with people. People are just drawn to her like a magnet.’”

It appears that DeGeneres and her girlfriends would have a lot of laughs at the actor’s expense, who eventually cottoned on.

“I remember you’d be, like, cracking up,” she told DeGeneres, “and I’d be like, ‘Why are they laughing at me?’”

“Really, you didn’t realize I was gay?” DeGeneres asked Mullally.

“I did not, no,” the actress replied.
