Beyonce celebrated her 35th birthday by throwing a Soul Train-themed fancy dress party attended by stars including Usher, Kelly Rowland and Alicia Keys. 
The Crazy in Love singer turned 35 on Sunday but she kept the celebrations going until Monday when she got dressed up in 70s-style clothes for her bash, which paid homage to the U.S. music variety show. Former Destiny's Child star Kelly channeled disco star Donna Summer in a low-cut gold jumpsuit.

"Thank you everybody for coming. Y'all did such an incredible job committing and I'm so happy to be here," Beyonce said before looking at Jay Z and saying "Thank you, baby."A video posted by BeefALERT (@beefalert) on
