Miming Ashlee won't go back on SNL

Singer Ashlee Simpson snubbed Saturday Night Live producers' offer to perform on the hit show again, after her October lip-synching scandal.

Simpson, aged 20, was mortified when a guide track she was using started without her and led to her dashing from the live show's stage in tears of embarrassment.

Her father and manager Joe Simpson later claimed she was suffering from acid reflux disease, which is why she decided to use a backing track.

Appearing at the Billboard Magazine Music Awards in Las Vegas on Wednesday, Simpson boasted: "I'm not going back to SNL. They asked me back. But I'm not going back. I figured I probably got the highest ratings for them this season."
