The 'Keeping Up With the Kardashians' star decided to go for a bob just a few days ago to match her sister Khloe Kardashian, but she's already having second thoughts about the 'do because her new look doesn't make her feel "sexy" enough. 

Taking to her Snapchat account, the 37-year-old beauty said: "So what do you guys think of my short hair? I'm so annoyed that I cut it. I just feel cutesy in it, like cute, no not sexy. I don't feel sexy in short hair, I feel sexy with long hair. It's cute."

And it seems her lack of sexiness is bothering her as she later took to her Twitter account the vent about her bob, writing: "Wait I miss my long hair (sic)."

Although she's not loving her hair right now, Kim is impressed with her body as she recently admitted that her sisters are jealous of her washboard abs and killer curves. 

Taking to Instagram earlier this week, Kim asked: "Wait, what was that Kendall?"

To which her half-sister Kendall Jenner replied: "I'm really concerned, I don't think you're eating. You're so skinny."

Her younger sister Khloe - who gave birth to her first child True three months ago - chimed in: "I've never seen a human being look as good as you. You are a walking FaceTune doll. I've never seen a skinnier person in my life than Mrs West. Well, Kendall but that's natural, you, that takes work to look like that and that's amazing."

Although Kim - who has three children; North, five, Saint, two, and Chicago, seven months, with her husband Kanye West - appeared to be lapping up the compliments, she is adamant she's not lost that much weight as she's still 119lbs. 

She screeched: "You guys, I'm not that skinny! I'm down to 119lbs but I will say that I am less when I take out my hair extensions so I don't have them in now."
