Andy Cohen has the power as executive producer of the Real Housewives shows and host of Watch What Happens Live.

But even Andy had to admit he's been wrong about the casting of certain ladies as he revealed in the upcoming Bravo special What Happens Live: Bethenny Turns The Tables, which airs May 26.

The talkative host confessed to Bethenny that he prevented Lisa Rinna from appearing on the first season of Real Housewives Of Beverly Hills - even though she'd made it as far as the first casting tape - and didn't think that she, Bethenny, would be an asset on the New York version either.

Confessions: Andy Cohen admitted to Bethenny Frankel (pictured with him on May 14) he's been wrong about casting choices on the upcoming special What Happens Live: Bethenny Turns The Tables, which airs May 26

Bethenny, straight talker that she is, managed to squeeze the information out of Andy during their sit-down chat.

'You know Lisa Rinna was on the first casting tape for Beverly Hills,' Andy confessed.

'In the first season of Beverly Hills, I thought "I don't see it. It's weird. It's not what this show is,"' he continued, adding: 'But then last year I wanted her on.'

First impressions: Andy said that he actually BLOCKED Lisa Rinna, left, from appearing on the first season of Real Housewives Of Beverly Hills and initially didn't want Bethenny, right, on the New York version

Divas unite: The 51-year-old Lisa lent her glamorous presence to the 2015 NBCUniversal Cable Upfront in NYC alongside her fellow Housewives Lisa Vanderpump and Kyle Richards on May 14

Finally made it: Lisa joined the fifth season of RHOBH but probably would have appeared on season one had Andy Cohen not nixed her chances

That wasn't all - Cohen told Bethenny that he initially didn't want her on Real Housewives Of New York City.

'Well, I was initially wrong about you,' Andy said. 'Because I, initially, when I saw the first casting of New York, was reticent about you because you had been on The Apprentice.

'And I thought that that was weird at the time. Isn't that funny?'

Outspoken: The former Days Of Our Lives star is known for saying her mind and got into a heated battle with troubled Kim Richards (not pictured) for calling her an 'addict'

Change of heart: Andy said that he changed his mind about Lisa and wanted her on the show

Wrong: The chatty talk show host told Bethenny, 'When I saw the first casting of New York, was reticent about you because you had been on The Apprentice' but he changed that tune too

He, of course, has changed his tune and stressed that Bethenny was 'born to be a Housewife.'

'I’ve been wrong a thousand times,' Andy didn't hesitate to say.

An Atlanta Housewife almost didn't make the cut thanks to Cohen's sharp observations - Kim Zolciak. The reason? He thought she looked too much like a country singer.

'I didn't get Kim Zolciak in the initial casting of Atlanta. I did not get... We have this white woman. I just didn't get it,' he said.

Andy was also quick to share that there was one lady he wanted as a Housewife on the New York show and didn't get.

'We almost had an amazing black woman. Anyway, they fell through, so maybe next season (sic),' he added.
