"Well, time flies when you\'re friends with Stephen Colbert, and last night I went to his show, The Colbert Report, to see him, and it didn\'t end well."

Sadness as Jimmy Fallon announced on his show last night that his BFF stint with Stephen Colbert, which kicked off in March, had met its expiration date.

"Sorry guys, I'm a little bummed tonight," Fallon told the audience. "Six months ago, I made a best friend and I wanted to be best friends forever. But he said, 'That's too much of a commitment. Can we do six months?' I said 'Deal, let's do this.'

"Well, time flies when you're friends with Stephen Colbert, and last night I went to his show, The Colbert Report, to see him, and it didn't end well."

"Wait a minute, we became friends on March 3rd, so that means it ends on…Sept. 3?!" Fallon said. "Oh my God, we're no longer best friends!"

"It's over Jimmy," Colbert chimed in.

The two song and dance men belted out a rendition of "Somewhere Out There," Fallon kicked off the song as Colbert joined in.

But don't expect Fallon or Colbert to let ratings hungry CNN chat show star and sometimes newsman Anderson Cooper try to replace what they had just yet.

"It's too soon, Anderson," both quipped.

Take a look below.

Jimmy and Stephen Colbert, whose six-month best friendship just expired, long for what they had through song.
