Even Andy Cohen Can't Resist Poking Fun at First 'Housewives' Reunion: 'I'm Pretending to Be a TV Host'

Andy Cohen looks back at his first Real Housewives reunion — 10 years ago!

Watch What Happens Live host Andy Cohen is used to putting his celebrity pals on the spot during their visits to his popular Bravo late-night show — often asking to “open the vault” on embarrassing photos from their past.

So when PEOPLE and Entertainment Weekly’s Editorial Director Jess Cagle stopped by Cohen’s mobile WWHL unit, it was only fair for Cohen to face some embarrassing photos from his past.

Among the many thrown Cohen’s way? A snap from the first Housewives reunion — 10 years ago!

As Cohen explains, it was The Real Housewives of Orange County‘s second season. Then having only hosted a few online videos, the 48-year-old’s move to primetime TV was the first step in what would be a major new career.

“It was a real big deal,” Cohen said. “I was really nervous and you can see it on how my lips are. If you ever see the show, I am trying to be comfortable and my face is a little tense. I’m trying to be relaxed — I’m, like, pretending to be a TV host. ”

As for the other photos, Cohen had a good sense of humor — making fun of his hair and telling some secrets of his childhood.

And when Dolly Parton shows up in one snap? To quote Cohen, it’s “incredible.”
