The A-list ladies at last night's Tiffany & Co. Rodeo Drive store renovation party looked like a million bucks—and for good reason! Reese Witherspoon, Halle Berry, Kate Hudson and Sofia Vergara were collectively dripping in over $2.4 million of jewelry from the beloved designer!

Jen might've been sparkling the brightest of all in $1.675 million worth of jewels, including a necklace, bracelets and two rings from the Tiffany Masterpieces collection.

"I've always loved Tiffany's," the Miracles from Heaven star told E! News. "I mean, growing up in West Virginia the idea of Tiffany's just seemed so far away, so glamorous, so exciting. And its always held that for me so I'm just happy to be here on Rodeo Drive with these fabulous ladies and get to chat and sparkle."

Reese, who was wearing a pink sapphire, rubellite and diamond $425,000 Tiffany Schlumberger bracelet and gold and diamond earrings from the Tiffany Masterpieces collection, enjoyed catching up with her fellow actresses and supporting Tiffany & Co. at the same time.

"I just started working with the brand about a year ago because they hired their first female creative design director [Francesca Amfitheatrof] for this iconic American brand," the Oscar winner said. "And it's so great because women are the ones that wear the jewelry!...So it's great to have a woman designing, and she's so creative and interesting and awesome, and I've gotten to spend a ton of time with her and travel with her. She just knows what women love: gorgeous jewelry, statement jewelry but also every day jewelry."

Sofia's $130,000 gold and diamond fringe necklace likely falls into the statement jewelry category, although we'd happily wear it every day if we could afford it!

Kate Hudson wore a $195,000 diamond necklace from the Tiffany Masterpieces collection, a $135,000 gold and diamond bracelet and a ring with a pink tourmaline and diamonds. Camilla Belle and Gal Gadot also wore jewelry from the designer, but Tiffany & Co. wasn't just outfitting the ladies...

Liam Hemsworth, Matt Bomer and Jack Huston each wore a watch from the Tiffany CT60™ collection. Liam, who came out to see a friend's artwork and photography, is pretty minimalistic when it comes to his accessories.

"I wear a necklace that is—it was from a very special person in my life," he told E! News. "And that'll probably be the only item that I always wear.
