Caitlyn Jenner's family have found it ''really hard'' to see her getting upset as she films 'I'm A Celebrity... Get Me Out of Here!'.

The 70-year-old reality star is currently in the Australian jungle filming for the British reality show, and whilst her family - including Kendall and Kylie Jenner - are rooting for her from back in America, they can't help but get emotional when they see her having a tough time.

A source told MailOnline: ''When she first went in it was really hard for them to see her upset, just because she is normally the complete opposite, so upbeat and positive.

''Caitlyn is being completely herself in the jungle and that is why the public are loving her. She is extremely kind and generous so it's no surprise that she isn't involved with any of the arguments in the jungle!''

The comments come after Caitlyn's daughter Kendall, said she is ''always rooting'' for the 'I Am Cait' star, who was known as Bruce Jenner before undergoing gender reassignment.

She wrote on social media: ''Always rooting for you [emoji heart] strongest person on the planet

''just cuz I am not posting doesn't mean I'm not supporting.

''I love my dad! Everyone chill (sic)''

Meanwhile, being in the jungle also means Caitlyn is missing Thanksgiving on Thursday (28.11.19), as it isn't celebrated in the UK so her fellow campmates won't be ringing in the special American holiday.

And her close friend and business partner Sophia Hutchins, 23, has said it will be ''weird'' celebrating Thanksgiving without her.

She said: ''I'm having Thanksgiving without Caitlyn this year, which is really weird. I'm hosting it at our house with some of my family and my good friend and his family, so it's going to be different this year.''
