Charlize Theron trolled Kylie Jenner, claiming she looks like the makeup mogul, who didn't seem to mind being trolled by the veteran actress one bit. Taking to her social media account, on Wednesday, she posted a side-by-side photo of herself and the E! reality star.

In the Instagram post, Theron is seen sporting a bright red lip that looks as if it has been applied by August, her 5-year-old daughter. Aside from being slightly outside of the natural lip line, the Academy Award-winning actress also has a touch of lipstick on her cheek.

This post-makeover selfie is accompanied by a screengrab of Jenner wearing a pink lip. "Who’s who?" Theron captioned the post, implying they are both identical. It is worth noting this was all in good fun, as the Kylie Skin founder liked and commented on the post with quite a few lipstick kisses and crying laughing emojis.

The comments section was teeming with sweet remarks from the actress's famous friends, including Chanel makeup artist Katie Lee who commented "Everything" on the photo. Actress Jamie Alexander couldn't resist commenting on the snap either, writing "nailed it."

Theron's social media followers are more used to seeing the actress share a series of throwback photos, some candid shots, and a glimpse of her two sweet kids. The recent post, on the other hand, was a treat fan of both celebrities.

Theron's fans gushed over the actress's look in the comments section on Twitter, with one of her followers calling her their heart, noting that she is more beautiful than Kylie and her eyes are gorgeous. Another Twitterati noted that they couldn't even see the difference. Theron unveiled this look on Twitter last month just before the People's Choice Awards.

In Oct. Theron posted two images on her Instagram account featuring her daughter taking a crack at applying makeup. She jokingly warned makeup artists of impending competition from her daughter. As expected, the makeup was uneven and smeared, with the Mad Max: Fury Road star sporting mascara, eyeshadow, lipstick, and blush, Fox News reported.

Kylie is no stranger to sharing videos of her daughter Stormi Webster doing her makeup on social media. In Oct. last year, the beauty mogul shared a clip of Stormi giving the “Charm” hue a shot. The toddler starts to put the application in her mother's mouth, and Kylie helps her out by telling her to apply it only on her lips.

Fans of Charlize Theron will be waiting with bated breath for the next round of who's who. What do you think about the Mad Max actress's latest post? Let us known in the comments section below.
