Mariah held a CD signing for fans at Universal City Walk in Los Angeles last night.
The very busy singer had double booked herself, though.
Sources reveal exclusively to PerezHilton.com that Carey was expected and had been confirmed to attend Us Weekly‘s “Hot Hollywood” party last night too.
Only she didn’t show!
Mimoo cancelled at the last minute, and we’re told event organizers and the mag were super upset.
Carey is on the current cover of Us Weekly, hawking her new record and talking about how she got that hot new body of hers.
