Kim Kardashian and Kanye West Pictures at 2012 Angel Ball in NYC

Kim Kardashian and Kanye West returned to NYC yesterday after a weekend trip to Italy, and they changed into their black-tie wear to hit the town right away. Kim donned a low-cut, bright blue gown to accompany Kanye to the Angel Ball, held to benefit Gabrielle's Angel Foundation, at Cipriani Wall Street. Kanye and Kim are often spotted hanging out with their pals Jay-Z and Beyoncé Knowles, but Jay and Beyoncé sat last night out. Instead, Kim and Kanye made the rounds with Beyoncé's sister, Solange Knowles, and mum, Tina Knowles. Also out for the charitable bash was Nelly and his partner, Ashanti. Bar Refaeli mingled with fellow model Jessica Stam before joining Kim and Kanye's table for dinner.

Kim was happy to be back in the Big Apple, and tweeted after the bash, "Lots of laughs at The Angel Ball with my best friends." Kim and Kanye had been in Europe to celebrate her 32nd birthday, which was Sunday. We marked the milestone by taking a look at Kim's best Instagram pictures. Kanye kept the fun coming yesterday by surprising Kim during their meal with another birthday cake.
