Andy Cohen lost his cool at Vanderpump Rules stars Lala Kent and James Kennedy on Watch What Happens: Live on Monday.

The usually unflappable Bravo host looked completely fed up as the out-of-control reality stars swore like troopers and even made claims about co-star Jax Taylor's health on the live Bravo show.

The show's censors were kept on their toes as Lala and James cussed throughout the episode, causing chunks of their conversation to be bleeped out.

Furious: Watch What Happens Live host Andy Cohen lost his cool during an interview with obnoxious Vanderpump Rules stars Lala Kent and James Kennedy

'Trainwreck:' The reality TV stars repeatedly swore throughout the interview, despite the host's pleas to watch their language during the live broadcast

And Andy had had enough and couldn't hide his irritation as he repeatedly told them to knock off the swearing and tried to keep the show on track.

While playing a celebrity guessing game called 'Who Is That Man Getting A Tan?', Lala continued to swear, causing the Bravo exec to throw up his hands and shake his head wearily as he looked into the camera in disbelief.

'Is there any way you could stop cussing,' he warned.

'I swear to God, you're driving me nuts.'

And when a sheepish Lala insisted 'I'm sorry, it only happened...' he quickly shot her down with: 'It's happened like, eight times.'

A testy James also swore frequently throughout the show, including when a caller asked if he had been using Kristen Doute to get more screen time.

'It's not like I was banging her for four months and became a primary,' he said.

'We were together for a year and a half. We had a Christmas tree together last year. I don't understand...' and the rest of his sentence was bleeped out.

Later, when another caller also started swearing live on air, an exasperated Andy said: 'Great, now you're cussing!'

Their co-star Jax Taylor was live-tweeting during the show, calling their behavior 'embarrassing' and labeling the episode 'a trainwreck' on Twitter.

'I've never in my life seen anyone try and be more relevant...what a trainwreck,' Jax wrote.

He added: 'This is the most embarrassing episode of @BravoWWHL I have ever seen. @Andy I'm so sorry on behalf of our real cast.'

And he threw in criticism of Vanderpump Rules' production company Evolution Media, adding '@Evolutionusa disgrace.'

'Worst @WWHL even @Andy looked bored. Embarrassing,' he wrote, adding 'and lala stop saying homie you're white.'

Andy read some of Jax's tweets to James and Lala during the show.

When a caller later asked Lala if she'd ever hook up with Jax, she replied: 'Ewww.'

'I know a little secret. After hearing what he just tweeted, I know your secret, Jax... And if anyone else knew about your little secret, they wouldn't either.'

James then blurted out a claim about the bartender's health.

Andy later announced his obnoxious guests were the 'Jackholes of the Day' for disrupting the show with their constant cussing.

And when one caller on the After Show suggested Lala had a future as an attorney, Andy scoffed.

'Lala has presented herself as a very intelligent person and incredibly capable of distilling through the muck so she can find the truth...I could see her as an attorney,' said the audience caller.

'You could see her as an attorney?' a shocked Andy said.

Chaos: The Vanderpump Rules stars swore throughout the show, causing many of their remarks to be completely bleeped out by the show's censors

'Wow. I guess you're watching a different show than me tonight.'

As the audience laughed, James buried his head in his hands and Lala shot the host a withering look and snapped back: 'Oh, funny. We won't go that far.'

'It is just me?' Andy said into the camera, shaking his head.

But the audience watching at home seemed to have a similar reaction, with Andy retweeting some of the funniest tweets without comment.
