Watching as the 28-year-old got down to hosting duty with Mario Lopez were her mum and dad – Kris and Bruce Jenner – and big sister Kim. The 32-year-old brought along her music star beau, Kanye West, and the two lovebirds whispered to each other as Khloe did her thing on stage.
Khloe's little sisters Kendall and Kylie were also in the audience – the only ones missing from the family group were Khloe's little brother Rob and her big sister Kourteney. The absent members of the clan could easily have kept up with the action, though, by looking at Kim's Twitter.
She posted several updates, unclosing a picture of her with sisters Kendall and Kylie in their seats. "XFactor we're in the building!!!! @kyliejenner @kendalljenner," the caption accompanying the picture read.The reality star also posted a picture of her sister on stage, writing "Khloe looks stunning tonight on X Factor! So proud of you @khloekardashian!!! You were born to do this!"
"Aren't you guys excited about Thanksgiving?" said Khloe, opening the show. The brunette looked glam in along sleeved white dress which showed off her curves perfectly.
Khloe's flirty banter and her family's show of support came after she had a scare earlier in the week. On Tuesday A letter addressed to Khloe containing a suspicious white powder was intercepted at the CBS studios where The X Factor is filmed. According to celebrity website TMZ the letter arrived in the morning "and the FBI soon arrived to inspect the mystery substance". The substance in the envelope was apparently found to be harmless, however.
Khloe has been hosting the X Factor for three weeks now. Rumours started in October that she would be taking on the presenting job opposite Mario Lopez. She finally confirmed the news on her Twitter saying: "The rumors are true... I will be hosting @TheXFactorUSA this season! I'm thrilled, overjoyed and of course a little nervous about this new step in my career, and I can't wait to get started. Wish me luck!
