Cynthia Bailey is caught lying to NeNe Leakes about Kenya Moore in hot mic ...

NeNe Leakes and Cynthia Bailey's friendship has been left in tatters after a dramatic season 11 of Real Housewives of Atlanta.

And Sunday night's finale episode exposed some of why NeNe had accused Cynthia of being 'sneaky' and a 'liar' on Instagram Live last month.

Cynthia was caught on a microphone trying to cover up the fact she had invited NeNe's rival Kenya Moore - who left the show after season 10 - to an event without her knowledge.

'I’m supposed to act like I didn’t know Kenya was coming,' Cynthia was heard whispering to boyfriend Mike Hill at the launch of her signature peach Bellini drink for Seagram's.

Cynthia had earlier appeared shocked when Kandi Burruss brought Kenya along with her saying: 'Now Cynthia, you said you wanted Kenya here and here she is,'

Off camera she was caught with Kandi trying to cover things up.

'I just want to make sure we was on the same page, setting up how Kenya got here,' she told Kandi.

Kandi repeatedly warned Cynthia during the exchange, 'I’m mic’d, I’m mic’d , I’m mic’d , I’m mic’d.'

Watching the episode before it aired, NeNe was upset to see Cynthia's conspiring and took to social media to put her friend on blast and declared the friendship was over.

'I don’t have no hate in my heart for Cynthia,' NeNe said. 'We are coworkers from this day forward. I don’t have any reason not to speak to her, I’m happy to not speak to her. I’m happy to speak to her. But anything else further than that, it’s not going to happen. No. We are coworkers.'

She also unfriended most of her castmates. 

Kenya, 48, surprised many of the women on Sunday's episode by arriving at a launch party for Cynthia Bailey's signature peach Bellini drinks for Seagram's.

'Oh, I think a monster's here,' said NeNe, 51, as soon as she saw her nemesis, wearing a figure-hugging bright orange dress showing her pregnant belly.

NeNe – who was joined by husband Gregg, 64, for one of the first times since his cancer battle – quickly blamed Cynthia, 52, for the unwanted surprise.

'This is a bunch of bulls*** that's Cynthia's doing,' she moaned. 'She didn't tell me because she did not want me to know.'

Porsha Williams, 37, noted: 'I think NeNe saw Kenya and immediately got p***ed at Cynthia. There's about to be some s***.'

NeNe initially made do with making over-the-top compliments about Kenya in a snide manner, with close friend Marlo Hampton, 43, pretending to stick her fingers down her throat at seeing the show's former troublemaker.

Cynthia insisted it was a surprise to her, too – although cameras picked up her whispering to boyfriend Mike Hill: 'I'm supposed to pretend like I don't know Kenya's coming.'

She even said onstage during a toast that Kenya 'surprised me' – with NeNe's rage escalating when her rival took the stage to toast the 'mogul' and 'boss.'

'It's just another way to be a f***ed up friend,' NeNe complained of Cynthia, assuming she allowed it.

It got so bad, NeNe even stopped Gregg from going onstage when Cynthia called him out to show 'some love' during his health troubles.

'That was pretty embarrassing. I
