However, there were also a couple of non-celebrity attendees who caught fans’ attention. Spears’ new sister-in-law Fay Asghari, 29, turned heads at the wedding and went viral on the internet thanks to her beauty and heartfelt wedding congratulations to older brother Sam.

So what do we know about Miss Asghari?

She is a registered nurse (and not the only one in the family!)

Asghari is a registered nurse and an entrepreneur. She is the proud owner of Be You Med Spa aesthetic clinic in Beverly Hills, which provides Botox, filler, thread lifts and other services. She also trains others on how to provide beauty services, as seen from her official Instagram profile.

However, she is not the only nurse in the Asghari family: her sister, Maddie, has the same occupation. Good genes and talent definitely run in this family!

She is an Iranian-American and very close to her brother

The Asgharis are of Iranian heritage and Fay is reportedly the youngest out of the four siblings, with Sam being the only brother in the family.

As seen on her Instagram page, Fay is apparently close to all of her siblings, but seems to share a particularly close bond with Sam.

Recently, the youngest Asghari shared a heartfelt birthday shoutout to her big brother, writing, “Happy Birthday to my brother @samasghari. The world is a better place with you in it. Thank you for always being my best supporter and my best friend. I wish you all the best in the world. Love you so, so much.”

She is also a commercial model and has over 137,000 Instagram followers

With her good looks and svelte figure, it should come as no surprise that Fay is also a part-time model. The cosmetician often shares magazine photoshoots on her Instagram profile, which has over 137,000 followers at the time of writing.

Last March, the two siblings also modelled for the LA-based brand Mister Triple X, where Fay walked the runway and Sam starred in the fashion label’s ad campaign.

Her boyfriend is also a famous surgeon

It’s not always opposites that attract: Fay is currently dating an American-Arabian surgeon Dr Amir Moarefi.

According to his Instagram profile, Moarefi is a board-certified eye surgeon and enthusiastic about “ocular and facial health aesthetics”. He had also been named by Los Angeles Magazine as a top ophthalmologist three years in a row and has almost 15,000 followers on Instagram.

The lovebirds are not big on PDA, but have shared several tender pictures of themselves together. In one of the wedding posts, we can clearly see Moarefi sitting beside her in the front row together with her mother and sisters.

Her boyfriend seems to be on brother Sam’s good side too. Apart from attending his wedding, Moarefi also previously posed for a picture together with the siblings (a post-workout snap, of course).

She had the most aww-worthy message for Spears-Asghari

In a recent Instagram post, Fay wrote a heartfelt congratulations for the newlyweds: “One of the most beautiful and emotional moments of my life was to watch my brother get married. I love you both so much.”

She also posted a picture of herself and singer Selena Gomez in a group photo as well as a picture of herself, Spears and Sam out for dinner, which she posted after their engagement announcement.

Will we see her in one of Spears’ famous Instagram posts next?
