The socialite turned 31 on Friday and celebrated with her friends and family in New York at Manhattan hotspot The Derby, where she was treated to a surprise performance by pop star Pink, who sang The Fugees' Killing Me Softly, according to EOnline.com.
Kardashian was also celebrating a career milestone, after announcing to fans that day that she has been offered a role in Perry's new movie 'The Marriage Counselor.'
In a post on her Twitter, the reality TV star told fans, "Big news!! I'm co-starring in Tyler Perry's new movie!"
'The Marriage Counselor' centers around a married couple – an accountant and an Ivy League-educated marriage counselor – whose relationship begins to fall apart after his displaced parents move in.
The marriage counselor, Judith, stops practicing what she preaches when she rekindles a relationship with an old college flame. Kardashian will play Judith's co-worker.
