It don't mean a thing if you ain't got that bling. On Saturday, Kelly Osbourne showed off her manicure and her new engagement ring on Instagram. Along with the glittering pic, she wrote, "Loving my new manicure. Thank you Es Nails."

Kelly designed the sparkler herself and modeled the custom Tiffany ring after one of her father's pieces of jewelry. "I designed it to look like an earring that my father wore when I was little," said Ozzy Osbourne's rockin' little girl. "I used to hold my finger up to his ear when I was little and say, 'I want a ring like that.' Now I have one!"

While news broke mid-July about that the E! Fashion Police host had gotten engaged to 29-year-old vegan baker Matthew Mosshart, the young couple has actually been engaged since Jan. 1. The purple-haired rock princess revealed to Us Weekly that Matthew proposed on a balcony overlooking the ocean while the duo was vacationing in Anguilla.

Kelly also told the mag that her parents were the first to know about the engagement, even saying that outspoken mom Sharon Osbourne approves. "She kind of expected it. Put it this way: Matthew's the only man I've brought home who my parents have liked more than me. Or who my dad hasn't called an absolute f-cker behind their back. Or tried to plot some way of getting rid of them!"

Previously, Kelly was famously engaged to model Luke Worrall before a bitter break up ensued in July 2010.
