Kanye West celebrated his 36th birthday in a low-key party on Saturday, June 8, without his baby's mama. Although Kim Kardashian could not make it to New York, the rapper was reportedly joined by Scott Disick, Jonathan Cheban and rapper Nas in the low-key birthday bash which was brought out by Beyonce Knowles and Jay-Z.

The heavily pregnant mother, who is no longer able to travel far due to health reason, wished her lover a happy birthday in an Instagram post. "Happy Birthday to my best friend, the love of my life, my soul!!!! I love you beyond words!" she wrote on Saturday. Along with the message, a photo collage was attached.

The collage contains six photos of Kim and Kanye in their sweet moments. Some of them show the couple gazing at each other sweetly, while another photo shows the couple raising their glasses for a toast. A picture of the pair with a sleek sports car behind them is also included in the collage.

Kanye was in New York to perform at an annual music festival, Governor's Ball, on Sunday, June 9. Kings of Leon and Guns N' Roses were also featured in the event.

On May 21, Kim wrote on her blog, "My final trip before I can't fly anymore! My mom and I flew to Paris to soak in the amazingness Paris has to offer before I can't travel anymore." The 32-year-old TV personality is expected to give birth to her daughter in July.
