Marzia Kjellberg

 ( 1992 Births ) 

Kjellberg's YouTube channel was one of the most popular in the beauty YouTuber; in May 2014, The Wall Street Journal reported that it attracted over 16 million viewers each month. The demographics of Kjellberg's viewers have been reported to be females aged 13-24, who use Kjellberg's videos as a reference. Kjellberg refers to her fans as "Marzipans".

Kjellberg appeared on her then boyfriend PewDiePie channel on various occasions. Felix, better known on YouTube as "PewDiePie," uploaded videos of the two playing video games and participating in video challenges together. In 2014, Kjellberg and Felix were part of an online marketing campaign for the horror film, As above, so below. While Felix's videos for the campaign involved gaming-related topics, Kjellberg's videos centered around a travel vlog angle of the couple's trip to Paris. Similarly, ABC had Kjellberg, among others, promote their new TV series, Selfie, via a YouTube marketing campaign.

On 22 October 2018, Kjellberg uploaded a video to her channel announcing her retirement from her YouTube career. In the video she mentioned that at a point during her YouTube career, focusing on the website kept her in a bubble that negatively affected her mental health, although she resolved to reach out to others. She ended her video explaining that she was ready for "something new in her life." After she uploaded her final vlog, as she decided to remove her videos; she left a comment on the vlog stating, "Having videos up, after making this decision, would have seemed like taking a step back. I've selected a few that I really liked, which I'm going to leave for a bit - for the 'adjustment' period - but taking my videos down, in my mind, needed to be done". Shortly before her announcement, her YouTube channel had accumulated over 128 million video views and just under 7.5 million subscribers.

• Her channel's video views previously peaked in August 2017, at around 570 million.

In a piece about fashion lines created by YouTube personalities, Tubefilter cited comments from Michael Fink, the dean of the School of Fashion at Savannah College of Art and Design, as well as celebrity stylist Allison Calhoun. Kjellberg's "Amore" clothing line was positively received by Fink, who stated "the gold zipper and heart applique of this skirt are right on trend, yet the A-line silhouette is timeless. You can't go wrong with this piece." Calhoun opined that "I'm personally not crazy about the patterns, colors, or cuts but I definitely can see the customer who might be. I also want to applaud Marzia and her designs for not being as topical as the others. It seems like she's making clothes that she wants to wear without a ton of inspiration from the outside world."

She was introduced to her husband, Felix Kjellberg, better known online as PewDiePie, by her friend Daizo. She began dating Felix in 2011, after e-mailing him and stating that she found his videos funny. Marzia moved to Sweden to live with him in October of that same year. Later, the couple moved to her native Italy, before settling together in Brighton, England. The couple lived there with their two , Edgar and Maya, as well as a hedgehog named Dogy. Their relationship has been highlighted by various media outlets, with The Globe and Mail writing that her "calm personality balances out Felix's general wackiness". On 27 April 2018, Kjellberg announced on Instagram that Felix had proposed to her; on 20 August 2019, the couple announced on social media that they had married.

While living in Brighton, their house in Japan was burglarized in late 2019; Kjellberg posted a statement online which included: "I know it is very materialistic, and should be happy with what I was left/have, but I can't hide the shock and sadness with all being taken away, just like that." In May 2022, Kjellberg and Felix fully moved to Japan. On 5 February 2023, the couple announced that they were expecting their first child, and they announced the birth of their son, Björn, on 11 July 2023.
