Kelly even got on the mic and sang!"

Younger sister Khloe wrote on her own blog that the group had celebrated at dinner before moving on to Tao, saying: "We were all passing the mic around, sharing birthday love for Kim - it was really cute!

"Somehow the mic kept coming back to me so I was on it for quite a while LOL. We all had a blast and it was definitely an epic Vegas night! (sic)."
