Linday Lohan's appearance on the latest episode of Saturday Night Live was meant to boost her faltering career. But viewers were quick to criticize the performance of the Mean Girls actress on Twitter.

I really wanted to give Lindsay Lohan a fair shake on her 'comeback' on SNL, but...she's awful, wrote one user.

Just got out of SNL. Lindsay Lohan could barely read her cue cards, another viewer posted.

The 25-year-old actress' performance produced a thread of social media buzz, most of which seemed to be negative. Rumors have circulated that the former redhead has undergone plastic surgery recently, after photos surfaced that depicted Lohan with fuller facial features. And viewers seemed to notice the change, according to Twitter.

So this has probably already been said but what happened to Lindsay Lohan's face? #SNL, tweeted one viewer.

Watching #SNL. Not to be mean, but Lindsay Lohan's face is a drug prevention ad, sad to say, wrote another Twitter user.

One of the most noticeable features of Lohan's performance was her heavy reliance, and difficulty with, reading cue cards during her scenes.

The only thing Lindsay Lohan seems addicted to is the #SNL cue cards, read one tweet during the show's broadcast.

Thanks to LL, we know where SNL keep their cue cards, read another.

This isn't the only recent SNL guest appearance to spawn vicious reviews. Pop sensation Lana Del Rey's performance in January was said to be one of the worst musical appearances in the show's history.

White Stripe's guitarist and The Raconteurs front man Jack White also appeared on the show Saturday night.
