Reality TV personality Kylie Jenner was more than excited to announce her graduation from high school.

The 17-year-old star took to micro-blogging website Twitter on Tuesday to share the good news with her fans, though she never posted anything about her school life on social media earlier, reports aceshowbiz.com

"I finished school last week...I know I never post on social media when I'm in class but that doesn't mean I don't encourage education! Because I do," she wrote.

A source said that Kylie continued her education after ninth grade in a home school program to earn her high school diploma.

In May, Kylie also defended herself against negative rumours about her education.

In reply to a fan's question about whether she would finish her school, she wrote: "I do school every weekday :) again don't believe everything you read."

At that time, she told her fans that she would graduate in "1 more month."
