Jenna Marbles Break Up with Max UPDATE: YouTube Star Hints at Infidelity as she Exposes her Ex & Vents via Twitter

Jenna Marbles (Jenna Mourey), the beloved YouTube star with over 8 million subscribers, has finally given her followers some insight into the real reason why she and her boyfriend of 4 years, Max "NoSleeves," really broke up back in December.

In a Twitter vent session that began on Sunday, the New York native hinted that Max's infidelity was the true cause of the couple's 2012 break up with the exposing tweet:

"Once a cheater always a cheater. We are never ever ever getting back together. Like ever. #weeeee"

Dedicated "Marbleheads" had come to know and love Jenna's ex, Max Weisz, through his frequent cameos in her countless comedic videos that she began making back in 2010 (with her first viral YouTube video,"How to Trick People into Thinking You're Really Good Looking," gaining over 50 million hits). Jenna's fan base, mostly consisting of preteen & teenaged girls, were deeply upset by the shocking news that she and Max were splitting, posting reactions like "MY LIFE IS OVER," "I feel like my parents are getting divorced," and "everything I know about love is a lie."

As a New York Times article profiling Jenna notes, "they were an attractive and playful couple. She cut his hair. He tried to put makeup on her. They wore elaborate Halloween costumes. It seemed like a teenage girl's fantasy of what it would be like to be grown up with a cute boyfriend and a job that consisted mostly of hanging around online."

Max used the fame that he gained from Jenna's loyal followers to create his own "spinoff" youtube channel, Max NoSleeves, that currently has over 468,000 subscribers.

When the break up news originally broke back in December of 2012, Jenna stressed to her fans that she and Max were still really good friends and that there were no bitter feelings. However, according to her latest series of tweets, Jenna's content attitude has seemingly changed over the past few months.

"I am not going to stay quiet anymore. You wronged me for the last time. You guys all know exactly what I'm talking about. I agreed years ago to let all of you be a part of my life. Every high, every low. I keep my most personal business private because it doesn't need to be out there. I can't always be as open as I want because I would never want to hurt another person. But I cannot even PRETEND anymore that I support (you know who's) piggy backed channel after the shit this kid did, does and continues to do."

Jenna vented with this statement Monday afternoon, which is presumably referring to her ex boyfriend Max whose "piggybacked" channel only gained fame because of his famous girlfriend in the first place. The Times reveals that Max is "making enough money from YouTube to support himself by following his ex-girlfriend's template: producing funny, low-budget videos on a strict schedule."

When Marbles first broke the news about her and Max's break up, she made sure to do so carefully and strategically, not wanting to portray Max in a bad light or crush her young followers' dreams of finding a love like their "idol" Jenna's.

"It was incredibly stressful," she told NY Times. "I had to tell these 13-year-old girls that I broke up with my boyfriend - who they love - and I wanted to do it in a way that wasn't going to hurt his channel."

While Jenna held back much of the details surrounding the break up at the time, she confirmed the split via the tweet:

"Wow. Max and I broke up after 4 years over BradTheLadLong. COOL."

BradTheLadLong is another fellow YouTube entertainer, and Mourey harshly commented on one of his videos with:

"You can't fu*king sing dude, and you're creepy as f*ck."

The comment appeared on jennamarbles main page, leading her loyal subscribers to follow their idol's lead and also negatively comment BradTheLadLongs video. This resulted in him being bullied with hate mail and even a few death threats.

As for Jenna and Max, the comment, which became a scapegoat, was rumored to be the reasoning behind their breakup. It allowed Max to look like the "good guy" for defending "YouTuber" Brad and shifted the blame. Until now, Marbles never led her fans to believe that Max did anything wrong in their relationship.

She ended her recent rant on a more uplifting and motivating note with:

"And for you young girls out there, never let anybody make you feel like you aren't worthy of happiness and love. There is someone in the world who wants to love you and only you for exactly who you are and I always have your back."

Although Jenna is grateful that she has somehow become the most-viewed YouTube star ever, with her random hilarious videos bringing in over 1 billion views, the internet sensation mentions that fame has its ups and downs.

"Sometimes I like to think it would be nice if you just had a character and your personal life was your personal life," she said. "My life is definitely out there, you know?"

As ABC News notes, 26-year-old Mourey has more Facebook fans than Academy Award-winning actress Jennifer Lawrence, and her more than 1 million Instagram friends top even Oprah Winfrey. She has built an online empire practically from her bedroom by posting videos, sometimes while intoxicated, on pretty much anything she feels like.

"It's ridiculous what I do," she said. "It's ridiculous that a lot of people watch it and what I put out on the Internet is ridiculous, yeah."
