When Kim Kardashian featured businesswoman and daughter of music mogul Irving Azoff, Allison Statter, 40, on her Instagram recently, referring to her as a 'best friend', even devoted fans of the reality star were left puzzled. Many had never heard of Statter before, and were familiar only with Kardashian's more high-profile close friends, and were therefore surprised to discover that Statter was not only superior to them all - but had been around the longest. Allison is in fact perhaps the oldest friend Kim has, being close with Kardashian since they were both children. The sudden appearance on Kim's social media has drawn massive attention to the quiet mom-of-three, who is now embracing the 'exposure' her long-time friend has brought her.

So just who is Kim Kardashian's friend, Allison Statter? Read on to find out.

6 Allison Statter Lives A Mostly Normal Life

Though Alison Statter comes from music royalty, being the daughter of legendary producer Irving Azoff, she is relatively low-key compared to friend Kim. They grew up close together in the LA area, and spent lots of time together as children.

Allison married her husband, Richard Statter, several years ago, and they share three sons together, living a 'normal' lifestyle in the Beverly Hills suburbs.

5 Allison Statter Has Her Own Highly Successful Company

Like friend Kim, she is also a very successful businesswoman. Allison is CEO of Blended Strategy Group, a Los Angeles-based celebrity and influencer marketing, public relations, and branding agency which she co-founded in 2015. Her young company has worked with several big brands, and continues to go from strength to strength, gaining notoriety in its field.

“We’ve made it to five years and we’ve managed to grow a business I’m really proud of,” Allison has said, and says the experience she has had in the industry proved invaluable. “I’ve been in the business for so long and I’ve seen its evolution,” she says. “I’ve been around since the days where we needed to hire a global pop star for millions and millions of dollars to leverage them for our marketing, to the emergence of bloggers to influencers, and now to many different forms of influencers. I feel really lucky I have had the education in real time and to have seen this whole evolution of how marketing works with influence at the center of it.”

4 Allison Statter Is Very Close To Kim Kardashian

Allison bears the title 'best friend' in reference to Kim, and certainly seems to back it up. The two spend lots of time together, regularly attending parties, events, dinners, and enjoying cosy nights in. Sweet snaps on Allison's instagram show a casual side to their friendship, which seems to be filled with plenty of affection, laughs, and in-jokes.

3 And Allison Statter Is Friends With Other Kardashian Sisters Too

Having known Kim since they were little girls, its only natural that Allison should be well known to the Kardashian clan. She appears to be close not just to Kim but to several of her sisters, too. In a recent Instagram post celebrating her birthday, Allison received a sweet comment from Khloé which read 'Happy birthday beautiful Al!!!!! I love you!!!!!!! You are such a magical soul!! I hope you know how loved you are by so many!'

2 Allison Statter Has Been Working On Collaborations With Kim Kardashian

As well as appearing on friend Kim's socials, Statter has also been working in collaboration with Kim on her Skims shapewear brand, and a special friendship collection for KKW Beauty. 'I feel so lucky that Kim asked me to do this collaboration with her,' Statter wrote on Instagram. 'We are so excited for all of you to get a piece of our amazing friendship through this collection! These are some of my favorite pictures from our fun (and fabulous) day shooting the campaign!!! Love you Kimmie!'

However, Allison was surprised when people suggest the collab was done to purposely draw attention to herself.

“It’s so funny to me,” Statter says. “People ask me ‘How did [Kardashian West] get you to do that? I’m like ‘What do you mean? She’s my best friend.’ If she asks me to do something, there isn’t anything I wouldn’t do for her. I didn’t make the decision to do that Skims video or the [makeup] collab to become public-facing. I did that because she’s my best friend and she asked me to do it, and I wanted to do it for her. And she would do the same for me.”

1 Allison Statter Is Surprisingly Pleased With Being 'Exposed' As Kim Kardashian's Bestie

You may think Allison would now be ducking from paparazzi after being outed as Kim's semi-secret best friend, but you'd actually be wrong. Statter doesn't necessarily fear the spotlight, and says she is embracing the attention:

“I realize that the collaboration has definitely exposed me in a different way than I’ve been exposed before, and I’m embracing it,” she says. “I don’t need the fame or the public persona to be what drives me. That, to me, is not what drives me.”
