Cheers!

Khloé Kardashian, wearing a sparkling mini dress, and boyfriend French Montana looked as adorable together as ever as they made their first joint red carpet appearance, at the reality star's third major 30th birthday bash. The event was held at the TAO nightclub in Las Vegas on the Fourth of July.

The two were photographed smiling several times at the party. Kardashian turned heads with her black sequined, zig-zag-patterned, cutout mini dress by Michael Costello, one of her favorite designers, paired with black pointed heels. By contrast, her rapper beau wore a white button-down dress shirt, white pants and white shoes.

"Thank you so much to everyone who came to TAO last night and helped ring in my birthday yet again!!!! How lucky am I?!?" Kardashian said on her Instagram page. "A major thank you to my friend @michaelcostello for making me look like a Barbie last night in my stunning sequin mini dress!!!!"

Kardashian received a slot machine and Independence Day-themed, four-tier, red, white and blue birthday cake. TAO employees cheered her on with signs spelling out "KHLOE."

She and her boyfriend reportedly began dating earlier this year and have appeared cozier than ever in recent weeks, including at her second major birthday bash on June 27, her actual birthday. The two partied on a yacht in New York with the Kardashian family and packed on the PDA. A day earlier, they celebrated at a pre-birthday bash at a nightclub, where the rapper gifted her a car and a diamond ring.
