Hollywood's 'It' Girls Get a Lift During Booby Tape Launch Party

Hollywood's "It" girls are full of secrets, but one they can't contain is their love for booby tape.

"The Hills" star Heidi Pratt, YouTube sensation Tammy Hembrow and Kylie Jenner's newly famous best friend, Stassie Karanikolaou, headed to a private party to celebrate the OG of keeping their tatas on fleek.

Inside The Party:

Heidi lead the way with her girls a blazin'.

The MTV starlet left her son, Gunner, at home and headed to the event, which was held at Stanley Social in Los Angeles on Thursday.

Heidi hit the pink-theme on the head with her silk shirt, baring a very deep v cut.

Sitting on a prop swing with a sign above her reading, "Stick together with Booby Tape," she's clearly happy to support the brand.

Tana Mongeau & Tammy Hembrow:

YouTube stars Tana Mongeau and Hembrow stopped to pose together with pink and white balloons in the background.

Standing inside a prop reading "Booby Tape," the blondes flaunted their hourglass bodies.

Mongeau is currently in the spotlight because of her upcoming wedding to Jake Paul, which takes place in Vegas this weekend.

Hembrow is known for her rocking body and fitness videos, but her fan base got bigger when she was carried out of Kylie Jenner's 21st birthday in a stretcher.

Stassie Karanikolaou:

Kylie's best friend, Stassie, showed off her curves with a tight bodysuit.

Baring the perfect amount of cleavage that peaked through the keyhole, she stunned with her piercing blue eyes and edgy look.

Stassie's tanned skin is from her recent trip with Kylie to Turks and Caicos.

The two made sure fans knew they were thick as thieves by matching their outfits every day.

Kylie even stepped in to defend Stassie when a fan body-shamed her.

Booby tape lifts and secures your girls in whatever desired position you seek -- and it's completely invisible underneath clothing.

Even Kim Kardashian has credited this technique for her big and voluptuous red carpet cleavage.
