Much to Justin Bieber's chagrin, Kim Kardashian is officially off the market, with the news today that she's engaged to New Jersey Nets forward Kris Humphries. Let the "K"-named babies begin!

After months of speculation about a possible engagement, Humphries proposed in Kardashian's bedroom with "WILL YOU MARRY ME?" written in rose petals. How original. Oh, and the ring? It's a walloping 20.5-carat diamond behemoth, because, as Humphries put it, "I just knew I wanted it to be big." (For reference, Kate Middleton's sapphire engagement ring from Prince William was a wimpy 18 carats.) Also, because these are the Kardashians we're talking about, matriarch Kris Jenner busted out two mini-horses covered in glitter to celebrate the engagement.

This isn't Kardashian's first trip down the aisle—in 2000, she was briefly wed to music producer Damon Thomas, though the union wasn't pretty. Kim herself seems optimistic about this one, writing in her blog, "OMGGGGGGG!!!!!!!! It’s true! I couldn’t be happier!"

No word yet on where the couple will live, though we eagerly await following the wedding plans on another season of Kourtney & Kim Take NY.
