As Westbrook herself advised back in 2016, she's not a college graduate, and she didn't she go to cosmetology school, either, which makes her meteoric rise to the top even more impressive. She always wanted to be on stage, but over the years, a passion for beauty grew. In 2010, she launched her channel, GlamLifeGuru (now simply called Tati). At the time of writing, she has over 9 million subscribers.

According to Naibuzz, Westbrook has amassed over 1.5 billion views over the years, which translates into serious money. Her videos generate an average of 450,000 views each, which brings in an estimated revenue of $2,250 per day or $820,000 per year from ad revenue alone. YouTube stars typically get paid $2 to $7 per 1,000 monetized views once the service takes what it's owed, with these views accounting for around 40 to 80 percent of total views. Google Preferred also contributes massively to YouTubers' salaries.

Elsewhere, Westbrook has released her own app and has had sponsorship deals for videos and Instagram posts. She's also launched her own skincare line, Halo Beauty, which sold out within just 12 hours and generated millions in sales. Celebrity Net Worth estimates Westbrook is worth around $6 million (so far).
