Is PARIS HILTON engaged? If so, she's not saying! When asked about the rumor that she's betrothed to BENJI MADDEN, "We're very happy, we're very in love," she responds with a chuckle.

Benji, Paris and her sister NICKY HILTON were just a couple of the A-listers to hit JADE JAGGER's Hollywood party launching the extravagant ice pick she designed worth a whopping $250,000!

The impressive ice pick is a part of Jagger's collaboration with Belvedere Vodka and boasts an 18-carat white gold hilt with 12 carats of diamonds and 42 pieces of pale sapphires!

"I was excited when Belvedere asked me to design this ice pick for them," Jagger says. "I drew my inspiration from medieval daggers and worked with the finest stones to create the pieces, which are fun and work to bring a pure experience to enjoying vodka."
