Ellen DeGeneres and Jennifer Aniston lock lips on camera

Jennifer Aniston and Ellen DeGeneres whipped fans into a frenzy when they kissed during a taping of The Ellen Show this week. 

The smooch happened after the pair discussed DeGeneres' recent lip-lock with Howard Stern, prompting Aniston to ask the host, "when was the last time you kissed a guy?" 

"When was the last time you kissed a girl on the lips?" DeGeneres countered. 

"I... I don't kiss girls on the lips!" the Friends star said, while DeGeneres shuffled forward on her chair and leaned in. 

With the audience cheering their approval, Aniston tucked her hair behind her ear and followed suit. 

"That's what they wanted to see! They've been wanting that for years!" DeGeneres said of the crowd. 

"You have such soft lips!" Aniston replied. 

"That's why I do what I do... no razor burn, soft lips," Ellen said. 

"I get it," said Aniston. 

DeGeneres also congratulated the Horrible Bosses star on breaking a Guinness World Record for reaching 1 Instagram million followers in just over five hours.
