Jack Osbourne is stoked he's made it into the Dancing With the Stars finals.
The 28-year-old TV star has been competing against a long line-up of celebrities for the coveted Mirror Ball trophy on the popular US programme.
He shared a spoiler alert on Twitter after his performance on Monday, revealing he had made it through yet another gruelling week on the dance floor.
"Spoiler ALERT!!!! Holy crap. I'm going to the mutha funkin finals!!!!!!!" Jack tweeted.
The star's sister Kelly logged on shortly after to heap praise on her younger brother, who was diagnosed with multiple sclerosis in 2012.
"Im so proud of my brother @JackOsbourne for proving to the world that nothing can stop you if you stay true to your self & never give up!" she wrote.
Kelly and the pair's parents, Ozzy and Sharon, as well as Jack's wife, Lisa, have been fixtures in the studio audience since Jack took his first turn on the dance floor in September.
Sharon has vocalised her pride for her son throughout the series, often urging her Twitter followers to vote. She admitted to tearing up during his last performance.
"I could not be more #ProudofJack!! @JackOsbourne's tango was phenomenal! @derekhough even stood up for him, I'm overwhelmed, in tears! #DWTS," she tweeted Monday night.
Jack will join High School Musical's Corbin Bleu, Glee star Amber Riley and comedian Bill Engvall in the finals.
