Kelly Osbourne reveres Lady Gaga and Nicki Minaj for "pushing boundaries" in their work.

The Fashion Police star is a fan of artists who spark controversy.

Although Nicki has been slammed by some critics for her exorcism performance at the Grammys last weekend, Kelly acknowledges the rapper for her creativity.

"I love [Nicki]," Kelly told OK! magazine at the MAC Cosmetics Celebrates The Viva Glam launch With Nicki Minaj and Ricky Martin in New York City. "People like her, Lady Gaga, they can't do any wrong in my eyes because they're pushing boundaries and they're teaching people about the past because they're reinventing what people have already done, but in a modern way."

Kelly is in awe of how Gaga, Nicki and other artists are positively impacting society.

"It's teaching people music history and creativity and inspiring young men and women in this world," Kelly explained. "So to me, they can do no wrong."

Kelly thinks that criticism is paired with accomplishment. In her opinion, Nicki should take detractors' comments in stride.

"Just like Lady Gaga and Madonna, no matter who you are or what you do you will always be compared to somebody if you're successful," Kelly explained.

Nicki and singer Ricky Martin will be promoting the latest Viva Glam beauty product range.

The iconic campaign has previously been fronted by the likes of Pamela Anderson and Gaga and supports HIV/AIDS charities by donating all profits of its products.
