Kim Kardashian may not have hung out with Beyoncé lately, but Kim's mother, Kris Jenner, 58, certainly has. Over the weekend, the reality star’s “momager” helped Tina Knowles, Beyoncé’s mother, ring in her 60th birthday in style. Kim Kardashian, meanwhile, was spotted in Los Angeles with fiance Kanye West on Sunday as they went to Mr. Chow for a dinner date.

Beyoncé and younger sister Solange had an extravagant Masquerade Ball for their mother in New Orleans, which reportedly cost over $100,000. In addition to Jenner, celebrities and friends such as Jennifer Hudson, Kelly Rowland and The Dream also attended the party at Muriel’s Jackson Square, arriving in horse-drawn carriages.

Tina Knowles arrived with her boyfriend, “V” actor Richard Lawson, with whom she first made her red carpet debut back in October. Just days ago, Beyoncé celebrated the birthday of her daughter, Blue Ivy, who turned two on Jan.7. While in Miami, she and Jay Z rented out the Jungle Island bird sanctuary in the Miami Zoo for their lucky daughter.

They can certainly afford to spend lavishly, as Beyoncé and Jay Z are reportedly pop music's first billionaire couple. The 32-year-old Beyoncé is raking in millions from her “Mrs. Carter” show tour. The Daily Star reported that she is set to earn approximately $116 million from the tour. She is also making millions as the new face of H&M, and her latest self-titled album has sold nearly 503,000 copies to date.

Meanwhile, Jay-Z has earned millions as co-owner of the 40/40 club, which has two locations in New York, and he is reportedly selling his small share of the Brooklyn Nets basketball team to extend his Roc Nation Sports representation business into basketball, according to Yahoo Sports.
