Jayde hinted at the split on Twitter: "Sometimes when you truly love someone you have to let them go. Just the same, Nicole reportedly "celebrated her breakup" with a 12-strong crew of girlfriends at Hyde Lounge in West Hollywood Friday night.
"Everything was totally fine before you came here, so you need to go back to wherever it is that you came from," Nicole sniped at Cavallari.
All three are signed on to shoot Season Six next year.
Model Kaitlynn who has been previously linked to actor David Spade, looked striking in a turquoise blue asymmetric mini dress with cut-out detail on the waist, which perfectly showed off her trim figure.
Her blonde tresses were styled into big glamourous waves and she opted for a natural make-up palette on her face.
However, the beauty accentuated her peepers with long false eyelashes and thick sweeping lines of eyeliner.
Meanwhile, the beautiful pair attended Kim Kardashian's ex Reggie Bush's wedding last week.
Brody shared a black and white photo on Instagram standing alongside the newly married couple, with the bride, Lilit Avagyan looking curvaceous in a white fishtail gown.
'My lover and my best friend': Kaitlynn shared a slightly different angle of the photograph (which had been flipped so made her ring seem on the wrong hand) where she kissed her fiance who said of his engagement, 'I couldn't be more in love with this woman and I can't wait to spend the rest of my life with her' Congratulations to the happy couple Brody Jenner and Kaitlynn Carter who have just got engaged. The model and blogger is a total beauty so we're not suprised Brody has put a ring on it!
And she looked even more fabulous here while on holiday in Indonesia donning a tiny two-piece bikini.
The black and white triangle number is by Velvet Sphynx and is a super classic style with its simple colour palette and design.
