The reports surfaced after the actors appeared in the recent Friends reunion special, and admitted they had feelings for one another while playing TV couple Rachel and Ross.
But now Jen has admitted she only found out that she was apparently involved romantically with David when she started getting cryptic texts from friends.
“Honestly, I was getting a couple of texts from people saying, ‘I thought you were on a break, LOL’, and I kept saying, ‘what are you talking about?’,’ the 52-year-old told Marie Claire Australia.
“And then I went online to see what was happening and I was like, ‘That is the funniest rumour that I never heard that got shot down in the quickest amount of time’”.
Last month, Jennifer set the record straight about her and David in an interview with Entertainment Tonight.
“That was bizarre,” she said. “I could not believe that, actually. Like, really? That’s my brother.”
She added: “But I understand it, though. It just shows you how hopeful people are for fantasies, for dreams to come true.”
During the Friends reunion, Jennifer and David explained they had both been “crushing” on each other during the show’s first season.
“At some point, we were both crushing hard on each other, but it was like two ships passing because one of us was always in a relationship, and we never crossed that boundary,” David said. “We respected that.”
Jennifer added: “Honestly, I remember saying one time to David, ‘It’s going to be such a bummer if the first time you and I actually kiss is going to be on national television.’ And sure enough, the first time we kissed was in that coffee shop.”
Instead of having a romance IRL, Jennifer said they “just channelled all of our adoration and love for each other into Ross and Rachel”.
