Here's something you might not realize: Celebrities are some of the best trolls on the internet.

Just think about it. They're online constantly, they have millions of people praising and criticizing them daily, and most of them won't suffer fools. Whether they're clapping back at insults, or slinging their own, they're A-list trolls.

You don't even have to be a fan of most mega-famous celebrities in order to appreciate their sharp responses and quick-witted lampoons online. For example, I've never listened to a full Cher album — I know, I'm sorry — but her Twitter game has turned me into one of her biggest fans.

If you can appreciate a good troll, here are nine expert celebrity experts you need to follow:

1. Rihanna

Rihanna doesn't have time for anyone's bullshit. Not now, not ever. And that's precisely what her online presence conveys.

Earlier this month, she jokingly shared an Instagram meme to lightly roast her fans who keep asking for new music.

But Rihanna has been coming for her haters for a long time -- like Piers Morgan, her exes, and just about everyone else. Not to worry though, Riri can handle herself just fine.

2. Chris Evans

Leave it to Captain Americato take an active stance against President Donald Trump.

If you follow Chris Evans, then you know he can't resist taking a shot at Trump whenever he does something particularly despicable, like when he insulted Dr. Christine Blasey Ford after her powerful testimony, discussed Russia's involvement in the American election, or after his press conference following the deadly Charlottesville protest in 2017.

Evans' ongoing political trolls definitely make him one of the best Chrises. Or, the worst. I honestly can't tell at this point.

3. Billy Eichner

He began as a major troll on the streets of New York City, but comedian Billy Eichner now takes to Twitter to air his grievances, most of which happen to be political these days.

Maybe you remember when he tweeted this message to help distract many of us from reality?

Or, perhaps you're more familiar with one of his more recent tweets slamming Senator Susan Collins.

Regardless, Eichner's roasts and digs will always be hilarious.

4. Ryan Reynolds

I probably don't need to tell you that Ryan Reynolds is amazing when it comes to trolling people online, so let's just take this moment to appreciate his greatest online hits.

Including that time he wished his wife Blake Lively a very happy birthday.

Or, when he wished someone else's wife a happy anniversary.

But his best trolling work is done when he comes for the thing he loves the most: his children.

5. Lili Reinhart

Lili Reinhart, has made herself extremely vulnerable online, opening up about issues with break outs, anxiety, and relationships. Naturally, she's become a target for harsh online criticisms, but she has taken to responding to even the rudest comments with brilliant humor.

When people questioned what happens in Reinhart's relationship in September, she kindly cleared a few things up.

The actress also wasn't afraid to clap back at a now-deleted tweet criticizing her weight a year ago. Time goes on, but Reinhart's wit prevails.

6. Chrissy Teigen

Pretty much everything model, cookbook writer, and social media maven Chrissy Teigen says online is funny. But Teigen is by far her most hilarious self when she's clapping back at her haters.

Like, that time she criticized Trump, and was told she doesn't live in the "real world."

Or, when she pretended she didn't know where her baby was.

And, when she pointed out the hypocrisy of a person following her if they're not really a fan.

7. Zendaya

If there's one person unwilling to sit back and take criticism, it's Zendaya. The actress has been calling out people on Twitter for years now, and has become known for her smart responses online.

She eloquently called out former E! News host Giuliana Rancic for making a racist comment about her hair in 2015.

Now, the actress mainly serves sarcastic comments to her followers, and has directed most of her energy online into urging people to vote. A more than worthy use of her massive platform.

8. Dax Shepard and Kristen Bell

There are tons of celebrity couples that love to troll each other online, but none do so as expertly as Dax Shepard and Kristen Bell.

Bell complains about Shepard's...unique home decorating ideas.

Shepard jokingly tweets about leaving Bell for a booze guzzling motorcycle-queen.

But, even better than when they're trolling each other is when they're coming after people who criticize their relationship. For instance, when Shepard blasted Starfor attempting to write a story about the possible decline of their marriage.

Bell later took to Instagram to comment, saying that she'd love to comment, but "its hard to talk with this ball gag in!" Classic.

9. Cher

Cher is the absolute master when it comes to singing and acting, but perhaps her greatest gift is her ability roast and toast everyone with the greatest of ease.

The singer and actress routinely criticizes Trump, but beyond political outrage Cher is willing and waiting to take on anyone who dares question her.

Please just take a look at the cornucopia of delicious trolls that Cher has given us:
