Khloé Kardashian and French Montana

is roaring into her 30s with a new man and a new plan.
The Keeping Up with the Kardashians
star, who turned 30 last week
, said she simply hopes for "happiness" to envelope her new decade.
"I just want positivity and having fun," she said. "I don't know. I'm only a couple days in to it."
So far, so good! Thanks, however, must be given, in part, to her boyfriend, French Montana
The couple have been practically inseparable since they began casually dating
in April – and he was again by her side at Friday's belated birthday celebration at Tao Las Vegas.
Wearing a black, sheer Michael Costello dress, the reality star and her beau cuddled up at a VIP table just off the Tao's dance floor, stopping only briefly when Kardashian was given a very Vegas style birthday cake.
With five of the club's go-go dancers donning shirts saying "Khloé 30" and holding up oversized cards spelling out her name behind her, Kardashian was presented a Vegas-decorated cake.
Meanwhile, deejay Eric Dlux cranked Montana's hit song "Pop That," much to the delight of the birthday girl.
Asked before the club what makes Montana so special, Kardashian told PEOPLE, "He's just funny, he's light and easy. That's what I need right now. He's fun. I like that he's always happy. Smiles are infectious and contagious, so I like that."
