Ellen DeGeneres and Jennifer Aniston locked lips on the set of her talk show.

Recently, Ellen DeGeneres and Reese Witherspoon argued over which one of them are better friends with Jennifer Aniston and it looks like Ellen decided to show off just how close she is with Jennifer by kissing her on the mouth on The Ellen DeGeneres Show.

Ellen, 61, took to Instagram to share a photo of her kissing Aniston, 50. 

She captioned the photo: "Find out how this happened. Tomorrow. @jenniferaniston"
