I love how Anderson switches is up from being this serious newsreader on CNN to talking about hot guys on Colbert 😂

[kjamison]

This is the most relaxed I have seen Anderson. Solid gold!

[mmlas]

Anderson is so damn handsome.. The ultimate silver fox 😍

[MichaelBerthelsen]

I say they BOTH are great at fashion! They both even matched their suits with their hair: white on black & graycscale!

I mean, Andy is right. Black suit for the summer, Anderson? I mean, come on. (Anderson giggles is my jam).

I'd like to see Cooper end an interview with the yam like that; he'd probably get fired but they'd play it in a loop for the next month.

I can see why their tour and friendship is a success, great dynamic guys.

The odd couple. It works so well. Really enjoyed these two with Stephen.

I love Anderson Cooper.... I don't really know who the other guy is, but he seems like my one friend who "keeps me fun, " yet needs to be picked up from the rough side of town at 7 a.m. Saturday morning with a fresh pair of underwear. :-p

[selvaracp]

Their friendship is cute... They dont care about any judgement... They both in interview with SC and in this skit are their natural selves... Constant petty fights... Beautiful

[Skyfox]

These two are like me and my best friend, always ripping on each other and having great fun at it.

[quantitativeease]

Adorable. I love Anderson Cooper but I've never seen Andy Cohen before. They have great chemistry!

[OldRaver]

Love this. Would love to hang out with those two, what a blast!

[yashiAR]

Always a good time when these two are together.

[tinamclaughlin]

Those two are awesome! Together, they are tremendous!

[aishab]
