Aussie actress and comedian Rebel Wilson, Orange Is The New Black star Taylor Schilling and 10-year-old actress Quvenzhane Wallis also make the list.
Fashion Police host Kelly tweeted that she was delighted to have been included.
"F*** yeah I made the @Forbes 30 under 30 list this year! Dadda I told you I would make you proud! @OfficialOzzy!!!! #HardWorkPaysOff."
Kelly, the daughter of Ozzy and Sharon Osbourne, said that it showed she had found success in her own right, writing: "No coat tails for me I did it!!!!!!"
Forbes wrote that "more good fortune" was on the way for the world's biggest boyband One Direction, with more gigs around the world and their third studio album, Midnight Memories.
Meanwhile, Rush actress Olivia Wilde - who turns 30 in March - was also pleased to have made the list for the final time she was eligible.
She tweeted: "So close to being too old for this. Thanks!"
