'She's such a b****!' Khloe Kardashian turns on Chelsea Handler in new preview for KUWTK

She's appeared on her talk show last year - even stepping in as host for her on her former series Chelsea Lately.

But in a preview for this Sunday's Keeping Up With The Kardashians, Khloe Kardashian has some harsh words to say about Chelsea Handler.

The 32-year-old said of the comedian: 'She's such a b***h' when talking with sister Kim Kardashian during their family vacation in Costa Rica.

Chelsea has spoken out about the Kardashians over the years; in January, she told Variety she thinks the famous family could be the reason why Donald Trump won the election.

The comedian told the publication that the media covers Trump so much so that he's being treated like an 'entertainer.'

Chelsea explained: 'We've turned into a reality show. I blame the Kardashians, personally; the beginning of the end was the Kardashians. The way there people have blown up and don't go away - it's surreal.' 

However, Khloe appeared on her Netflix talk show, called Chelsea, last July; she even posed for a cheeky Instagram photo with the actress.

In the preview clip for KUWTK, released on Friday, the family is seen enjoying dinner before a fire show.

The name calling started over their outdoor dining set up in Costa Rica, with attendees including Kim, Khloe, Kris Jenner and boyfriend Corey Gamble, Kourtney Kardashian and Scott Disick.

While at their tropical holiday, Scott secretly invited a girl up to his room.

After the Kardashian women found out her name was Chelsea, they decided to have a little fun with Scott.

Kim stars it off by saying: 'Did you guys hear what Chelsea said?' 

To which Khloe responds: 'Oh yeah. She's such a b***h' while an obviously uncomfortable Scott listens in.

'No, she was so nice,' Kim says,' to which Khloe responds, 'She was a b***h.'

Kim, with a smirk on her face, says: 'Oh Chelsea Handler. No, no, no, I'm talking about Chelsea Clinton, what she said when she was sticking up for Barron Trump.'

'That's nice that Chelsea did that,' Khloe agreed. 'I thought you meant Chelsea Handler.' 

Soon after Kim says: 'Let's cut the bulls**t,' but the conversation is temporarily paused as the fire dancers start their performance.

The Kardashian/Jenners were in Costa Rica in January.

Scott later tells the camera that he obviously knows that the 'girls know something's up.'

Adding: 'Nobody really wants to say what's on their mind. And if this dinner isn't awkward enough, these fire dancers have to come out and start doing hula hoops. I already felt like under fire.'

Scott and Kourtney are parents to three children together: Mason, seven; Penelope, four, and Reign, two. 

They were in a relationship for nine years before splitting up in July of 2015. 

The brand new Keeping Up With The Kardashians episode airs this Sunday at 9 pm on E!
