Reality TV star Kim Kardashian took to the streets with her basketball star husband Kris Humphries keeping a protective arm around her as they arrived at The Darby in New York City to celebrate the star's 31st birthday with plenty celebrity guests.

The star, who turned 31 on Friday, stuck to her signature long, loose dark hair over her shoulders teamed with an over-sized white bag and black heels, as she made her way into the restaurant with her husband Kris Humphries, according to reports.

Speculation has risen that the couple's marriage may be on the rocks after Humphries was spotted by on-lookers without his wedding ring after losing it shortly in an airport.

Although, it seems that Kim Kardashian and Kris Humphries are paying no attention to the recent split rumors which have dogged their marriage.

The couple reportedly appeared to be in martial bliss as they stepped out in New York to celebrate Kardashian's 31st birthday Friday night with her friends and family.

But her birthday wasn't the only thing she was celebrating. The star also celebrated her upcoming leap onto the big screen with a major role in Tyler Perry's new movie.

Kardashian, who has recently landed a role in the next Tyler Perry movie The Marriage Counselor, looked striking in a grey floppy felt hat, long fur coat and black trousers as she arrived at The Darby restaurant in Manhattan.
