For nearly one decade, Ross Geller and Rachel Green’s duo, played by David Schwimmer and Jennifer Aniston, were everyone’s most favorite couple on screen but no one knew they had feelings for each other off screen too.

Speaking to host James Corden during ‘Friends: The Reunion’, the two actors admitted they both had feelings for each other before their characters got together.

David said that they were always dating other people and never acted on their feelings.

"The first season I had a major crush on Jen, he said to which Jennifer replied that the feelings were reciprocated.

“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. We respected that,” Schwimmer said.

He went on to say, "When we had breaks from rehearsal, there were moments we would cuddle on the couch," he adds. "We would spoon and fall asleep on the couch and I kept thinking, how not everyone knew we were crushing on each other?" to which Courtney Cox and Matt LeBlanc replied that they definitely knew.

Aniston also said that she and Schwimmer would talk about whether their first kiss would be in character.

"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. Sure enough, first time we kissed was in that coffee shop. We just channeled all of our adoration and love for each other into Ross and Rachel."

Jennifer and David had joined the rest of the cast for the much-hyped Friends: The Reunion show. The reunion also featured several celebrity guests including Lady Gaga, who sang "Smelly Cat" with Lisa Kudrow. Justin Bieber also featured in the show along with Tom Selleck, who played Monica's love interest, Dr. Richard Burke.
