• Last night’s American Idol finale brought out THE BIGGEST vocal powerhouses (Ms. Beyoncé and Ms. Lady Gaga, of course) complete with uh-mazing performance outfits. Beyoncé NAILED IT in a to-die-for Zac Posen platinum gown while debuting her new single “1+1” and danced to “Crazy In Love” in a Swarovski crystal-encrusted Ralph & Russo dress. Lady Gaga wore a triangular headpiece replete with studs and loose chains, which sort of reminds us of the Tree of Souls from Avatar. Seriously, Google it. {Vulture}

• On her final show ever (*sniff sniff*), Oprah signed off in a custom coral L’Wren Scott dress with a dip-dyed chiffon belt. We think this fresh, form-fitting dress couldn’t be more perfect for her last goodbye. The bright color shows optimism for what lies ahead, and HEY! Don’t cry! QUICK, look at these photos of doggies in scarves saying inspirational quotes from her show! {Styleist}

• The Savannah College of Art and Design lined an ENTIRE reception hall with Manolo Blahnik shoe boxes. Let’s all ogle at this breathtaking photo, shall we? {Racked}

Everyone knows Kim Kardashian is engaged to basketball star Kris Humphries, BUT HAVE YOU SEEN HER RING? It’s 20.5 carats. Yes, you read that right. Kris designed the 20-plus-carat ring with jeweler Lorraine Schwartz, aaaaaaand we’re officially giving up on life. {Oh No They Didn’t!}

• Model/resident Brooklyn hipster Erin Wasson will launch a capsule collection with French retailer Zadig & Voltaire this September. The line will be sold exclusively on Net-A-Porter and will feature suede jackets, leather pants, cashmere, and more. {Racked}

• Suburbanites rejoice! Rachel Zoe’s line is coming to a mall near you (a bougie mall, anyway). Her new collection will be at ALL 41 Neiman Marcus and Bergdorf Goodman locations around the U.S. starting this summer. We die. {Elle}
