Glamlifeguru

Glamlifeguru's real name is Tati Westbrook. She launched the channel under the Glamlifeguru handle and has built it into one of the most long-running dedicated beauty channels on YouTube. She now uses the name Tati Westbrook publicly across her content, brand work, and social media.

In May 2019, Tati Westbrook posted a nearly 43-minute video publicly ending her friendship with James Charles, accusing him of disloyalty — including promoting a rival brand at Coachella instead of supporting her own supplement company, Halo Beauty — and of manipulative behavior. The video went massively viral and temporarily cost James Charles millions of subscribers in what became one of the most-watched YouTube controversies ever. It defined a turning point in the wider beauty community on the platform.

Yes. In 2020, Tati Westbrook posted a follow-up video apologizing to James Charles, saying she had been influenced by mutual friends — specifically Shane Dawson and Jeffree Star — into making and framing the "Bye Sister" video the way she did. She retracted many of her claims and said she regretted the damage the video caused him. It was a rare public reversal that generated its own wave of coverage.

Details by Tati (handle: @details.by.tati) is Tati Westbrook's own beauty brand, which she references directly in her social media bio. It represents her expansion from reviewing other brands' products into developing her own beauty line. The brand sits alongside her content work as a key part of her creator business.

Halo Beauty was a hair, skin, and nails vitamin supplement brand that Tati Westbrook launched in 2018. One of her stated triggers for the "Bye Sister" video was that James Charles had promoted a competing supplement brand at Coachella rather than supporting Halo Beauty, which she felt was a betrayal given their close friendship. The brand became permanently linked to that chapter of YouTube history.

Yes, Tati Westbrook is widely regarded as one of the pioneering beauty voices on YouTube, having built her Glamlifeguru channel in the early years of the platform's beauty community. Her format of in-depth makeup reviews, first impressions, and drugstore comparisons helped set the template that thousands of beauty creators now follow. Her sustained following over more than a decade reflects her status as a founding figure in that space.

Drugstore makeup reviews are one of Glamlifeguru's signature formats — she regularly posts content dedicated to affordable finds under $10 and honest breakdowns of what works and what doesn't from mass-market brands. She covers both ends of the market, from luxury lines like Natasha Denona to budget drugstore hauls, which is a big reason her audience spans a wide range of budgets. That balanced approach has been a consistent part of her content since the early days of her channel.

Tati Westbrook is married to James Westbrook, whose last name she took professionally. He has appeared in her content over the years and has been involved in supporting her channel and business ventures behind the scenes. Their relationship has been a steady presence in the background of her public-facing creator career.

Glamlifeguru's YouTube channel has surpassed 8 million subscribers, a milestone she highlights in her own social media bio. That places her firmly in the top tier of dedicated beauty creators on the platform by raw audience size. Her YouTube presence remains her primary platform, with Instagram serving as a secondary channel for product recommendations and shorter content.

Tati Westbrook is from the United States, and the overwhelming majority of her audience is also American. She has been based on the West Coast throughout her career and is one of the most widely recognized American beauty content creators in the YouTube ecosystem.
