Casey Anthony may well have been let off by jurors, but the vast majority of Americans took the case to social media Tuesday to express their displeasure and disbelief with the verdict.

Celebrities including Kim Kardashian, LeAnn Rimes, Mandy Moore and Harvey Levin took to micro-blogging site Twitter to show their disappointment over the verdict, which acquitted Anthony from first-degree murder, aggravated child abuse, and aggravated manslaughter.

The jurors, including five men and seven women, who heard testimony in the month-long trial and took nearly 11 hours, said We, the jury, find the defendant not guilty.

However, she was convicted for four misdemeanor counts of providing false information to law enforcement officials.

TV personality and actress Kim Kardashian tweeted: WHAT!!!!???!!!! CASEY ANTHONY FOUND NOT GUILTY!!!! I am speechless!!!

Singer LeAnn Rimes expressed her grief over the verdict by tweeting: Shocking this trial!

Another singer Mandy Moore tweeted: Woah! Shocked about the verdict in the casey anthony trial! Thought she was guilty for sure! Either way, tragic story ...

She further said: i'm from orlando and have been hooked on the trial the last few weeks. The defense team was abysmal! this is shocking! poor, poor Caylee.

Moore added: i thought the prosecution was stellar, obv not enough to convince the jury tho. how does that family come together again after all of this?

Media executive Bonnie Fuller tweeted: OMG! Now it's OK to party like rock star when your child has disappeared or has drowned + don't report it!

Casey Anthony: People going nuts. Cannot believe verdict, said Fuller, who is also the editor of Fuller added, the bar has been lowered big time on what it means 2 b a mom. So sad. Poor Caylee- guess no one cares.

Meanwhile, TV producer and lawyer Harvey Levin compared the case with O.J. Simpson case and tweeted: having covered OJ Simpson ... nothing really shocks me anymore. but this verdict really surprises me....especially how quickly it came.

Comedian Kathy Griffin said Wow. Ok, now this case has my attn. Not guilty? Really? I just assumed...

TV personality Star Jones tweeted: I believe in the jury system & accept verdict...but I can't take smiles from #CaseyAnthony right now. She may be NG...but her baby is dead!

English television host and comedian Sharon Osbourne expressed her shock and anger over the verdict, and tweeted: Casey Anthony not guilty??'s a disgrace. She'll probably get her own reality show now.

Casey Anthony was first arrested on July 16, 2008, and was charged the following day with giving false statements, child neglect, and obstruction of a criminal investigation. Anthony was accused of murdering her daughter by applying chloroform first and sealing her mouth with duct tapes. Caylee's death took place in June 2008.

The key point that worked in favor of Anthony was that the prosecutors failed to show sufficient physical evidence that Anthony killed her daughter. They argued that the three pieces of duct tape found with Caylee's skeletal remains were the murder weapon. But there were no fingerprints on the tape and the only unidentified DNA detected excluded both Caylee and her mother.

On the other hand, defense attorneys contended that an accidental drowning caused Caylee's death, and argued it was speculation that the tape caused Caylee's death. They further said that the state -- in a capital case -- must prove that murder was committed.

After the verdict, Anthony wept in joy in court and her lawyers praised the verdict and claimed justice was done. Attorney Jose Baez said this case proved why capital punishment doesn't work. He said he is happy that he could save a life.

The devastated prosecution sat in stony silence after spending hundreds of thousands of dollars on the case and weaving the story of Casey's guilt with remarkable conviction.

However, Baez admitted that there were no winners in the case.

The Casey Anthony case has got extraordinary media attention, and was regularly the main topic of many TV talk shows, including those hosted by Greta Van Susteren, Nancy Grace, Geraldo Rivera, and others. It has been featured on Fox's America's Most Wanted, NBC's Dateline, and ABC's 20/20.

Nancy Grace, who calls Anthony as tot mom and had been covering the case since the child's disappearance in 2008, reacted to the verdict saying: Now, it is our duty as American citizens to respect the jury system.... But I know one thing, if the defense sits by and as their champagne toast after the not-guilty verdict somewhere out there the devil is dancing tonight.

Grace, who hosts nightly celebrity news and current affairs show on HLN, also tweeted: I believe there's a little angel in heaven. My thoughts remain with #Caylee tonight.

Nevertheless, the mystery still remains over how Caylee, the bubbly little girl with big brown eyes, died.
