Kim Kardashian and Kanye West Spend Quality Time with Oprah Winfrey at Jimmy Iovine's Party

Kim Kardashian and husband Kanye West were spotted rubbing elbows with Oprah Winfrey at Jimmy Iovine's celebration, according to Yahoo! OMG.

The former American Idol mentor was throwing a huge star-studded birthday bash for his girlfriend Liberty Ross. The British model, 34, filed for divorce from husband Rupert Sanders in January after US Weekly exclusively revealed he had cheated on her with Kristen Stewart in July 2012.

"Oh no big deal," Kardashian quipped via Twitter. Along with the caption, the 32-year old shared a photo of herself sitting next to beau Kanye West, Winfrey and Diddy at the get together. A source reveals to Us that the group were laughing and talking for quite a bit on the couch. Kardashian and West have had quite the weekend. Two days earlier, the couple left baby North West at home as they enjoyed a double date with Tyga and Blac Chyna. The two couples grabbed dinner at Hakkasan in Los Angeles Friday.

Other celebrities in attendance at the big party included Winfrey's BFF Gayle King, Mick Jagger, R. Kelly, Steven Tyler, Dr. Dre, Xzibit and Mary J Blige. The insider reveals to US that the Rolling Stones rocker even showed his infamous moves, by dancing with King just before midnight as Winfrey snapped photos. The party began at 8 p.m. with the last guest leaving around 1:30 a.m. Kim and Kanye recently gave birth to their first born daughter who they named North West.
