Did Catherine Zeta-Jones Lip-Synch 'All That Jazz' During 2013 Oscars? Actress Gets Mixed Reviews For 'Chicago' Performance

Michael Douglas’ gorgeous wife glided down the red carpet on Sunday for the 2013 Oscars wearing a Zuhair Murad golden dress.

The actress looked flawless, but some wondered whether she had taken it to the extreme to look perfect with caked-on makeup and a fake tan.  

The real shocker came when the spotlight switched from host Seth MacFarlane to Zeta-Jones: Viewers were transported back to her “Chicago” days, as the actress performed “All That Jazz.”

She wore a short raven wig and “Chicago”-themed outfit, but by the time she had finished Twitter users were unimpressed with the actress' performance. Many felt she had lip-synched and that her performance was less than stellar when compared with those of the “Les Miserables” cast and Jennifer Hudson.

One commented that the rendition didn’t go too smooth, writing, “I think Catherine Zeta Jones could have used a few more yoga classes before that performance it was awkwardly tight #truth.”

Another person was disgusted with the 43-year-old Welsh actress: "Is this Catherine Zeta-Jones' petty attempt to perform with Les Miz? Because that's as close as she's gonna get. #tacky #ew #pathetic."

@ChelseaLupkin shared, “I feel very very bad for Catherine Zeta-Jones ... we all know she didn't sing like everyone else. Come on now.”

But not everyone dissed CZJ for her performance. She had plenty of fans support her Oscar routine.

@GiselleUgarte was impressed with Zeta-Jones and her style: “Catherine Zeta Jones will forever be my #GirlCrush. What a hottie #Oscars.”

@Silva1105 was excited that the “Side Effects” actress showed up on the stage in general: “I still can't believe Catherine Zeta Jones performed All That Jazz, omg!”

@klaines_ agreed: “I literally felt my eyes water when catherine zeta jones came out on stage im sorry i love Chicago.”
