Kim Kardashian Rocks Tight Dress, Flashes Ring At First Post-Engagement Event With Kanye West

Kim Kardashian knows what people want to see, so she lets them have it -- the bum and the bling.

The reality star and Kanye West made their debut as an engaged couple at the Dream For Future Africa Foundation gala at Spago in Beverly Hills on Thursday night. The 33-year-old new mom turned heads in a skintight white cutout dress that hugged her famous assets, and made sure to show off the 15-carat diamond ring with which West proposed to her on Monday .

Since the romantic proposal, there have been reports that the couple aren't planning for a long engagement, with sources telling TMZ the wedding will happen very quickly . Of course, that's not before they sign a prenup . Multiple sources told the website the couple are not signing the prenup because they believe the relationship might dissolve, but rather because they are both smart business people and it's just what those who are worth millions upon millions of dollars do when they get married.

Interestingly, while some reports estimate that Kardashian is worth $40 million and West is worth $90 million, other sources have told TMZ that it's Kim who is actually worth more. It could have something to do with the $100 million her father is rumored to have left the family when he died.

In the meantime, the couple seems very happy and Kardashian was practically gushing at Thursday's event , telling E! News, "I'm extremely happy. It's where I am at in my life and I hope people can see that because it's what's going on with me right now."
