Kim Kardashian's little brother ROB is going public with his new romance by showing girlfriend ANGELA SIMMONS off at his 23rd birthday in Las Vegas on Friday night (12Mar10).
The socialite and reality TV star has been dating rap star Joseph 'Revd. Run' Simmons' daughter for some time, but the pair chose to keep the romance quiet.
However, Simmons has agreed to join her beau on the red carpet at his Jet nightclub birthday bash at the Mirage hotel - and go public.
An invite to the big bash reads, "The first son of America’s favourite family will be joined by new girlfriend, Angela Simmons, who is making an appearance with her new flame for the first time."
