Blac Chyna celebrated her 28th birthday and her foray into the tech world with the debut of her new emoji app, Chymoji, at the Hard Rock Cafe in Hollywood last night.

Sporting a flowy black tunic and leggings, Chyna showed up alongside her fiance Rob Kardashian, who was in all black and a Yankees fitted cap. The newly-engaged couple walked the purple carpet together, being seen publicly for the first time since announcing Chyna's pregnancy.

The two couldn't keep their hands and eyes off of each other all night. "I just feel amazing, and I feel blessed," Chyna said. Her Chymoji app has more than 700 emoji's to choose from, with several different versions of herself, Rob and their new baby on the way. The social media star says each emoji reflects her life and she loves them all.

"I'm extremely proud of how through Glamroks was in developing my characters," Chyna stated. "My Chymoji app is an expression of my personality and diversity of life.

But of all the emoji's she's released, she announced she has two specific favorites.

"The one of King (her 3-year-old son with Tyga), and the one of me actually bouncing on Rob is one of my favorite ones," the future Mrs. Kardashian told reporters.

Rob followed with, "I just like money, anything with money. All of the one's with her hands in money, that's always good."

The event started at 9pm and celebrities continued to pour in and walk the carpet well past midnight. Everyone expressed their love and support for Chyna and her new endeavor.

"I love the baby one," Basketball Wives star Tami Roman said of her favorite Chymoji. "Outside of her love for Rob, I just think she is a boss b****. Nobody could have done this better than her."

"I just came to support my girl Chyna, I'm really happy for her, just super happy for all the things that are happening for her personally and professionally," friend and clothing designer Rosa Acosta told the Boombox. "She's doing fantastic work wise, she's killing it. And she's found love... I feel like she's on top right now."

Celebrity stylist EJ King of BET's docu-series About The Business also voiced his solidarity with the couple.

"I'm always here to support Chyna, I support my friends" he said. I love Rob, I love what they have and what they're building. I'm so happy for her."

Other guests spotted were Draya Michele, Michael Costello, and rapper Safaree. Chyna's BFF Amber Rose wasn't in attendance but she is also featured on the app, in a  emoji with Chyna showcasing both of them "sipping tea."

Tyga somehow didn't make it to the soiree.

After the carpet, everyone joined Chyna (aka "Angela Renee Kardashian") and Rob on the party level to celebrate her birthday; and for Chyna, "celebrate" consisted of water and snapping photos, considering there's a baby on the way. But at midnight, a cake was brought to Chyna's table and the DJ wished her a happy birthday, while faux-money with the socialite's face on it was thrown in the air.

The couple had fun--but didn't divulge any more information about a wedding date or a due date for the new Kardashian heir.
