Even stars can have celebrity doppelgängers.
Reese Witherspoon and Carrie Underwood proved this to be true after a fan mistook the 44-year-old actress for the 37-year-old singer.
The slip-up took place after a social media user, Noha Hamid, spotted the Legally Blonde star while eating at a barbecue place in Nashville.
"I swear, I see this, like, lady with her husband and kid, and I'm like, 'That looks just like a celebrity,'" Hamid said in a TikTok video. "And I'm trying to think who, and I'm like, 'Oh, Carrie Underwood?'"
Hamid couldn't fully see the celebrity because the A-lister was wearing a "big cowboy hat" and a mask. So, Hamid decided to solve the mystery and approached the celeb.
"I wait until she kind of goes back to her car so I can, like, ask her if it's her—not in front of everyone to blow her cover," Hamid said. "Then she's like, 'Hey! Oh no, I'm not Carrie Underwood. But have a great day.'"
Initially, Hamid thought the star was lying. It wasn't until later that she realized she had been talking to Witherspoon. The Oscar winner seemed to get a kick out of the mistake, too.
"To the woman in the parking lot who just asked me if I was Carrie Underwood: You officially made my day!" Witherspoon tweeted.
Underwood did, too.
"YOUR day?!?!?!?!" the Grammy winner replied. "That lady just made my whole life!"
Underwood and Witherspoon aren't the only stars to be mistaken for one another. To see celebrity look-alikes, check out the gallery.
In September 2021, The Beverly Hills, 90210 alum stepped out in L.A. with a new makeover that made many fans draw comparisons between her and a certain reality star.
Talk about reality TV worlds colliding.
Some fans can't help but point out similarities between Real Housewives of Orange County star Emily Simpson and Keeping Up With the Kardashians veteran Khloe Kardashian.
"I can see a little resemblance," Simpson told E! News in March 2021. "I think it's an overall thing. She's very tall and she's very curvy. We're very voluptuous. I'm not trying to look like her. I'm just trying to look like the best version of myself."
These stars both rock the red hair and, in this photo, a similar style.
And The Help co-stars look so alike that director Ron Howard mistook Chastain for his own daughter.
Chastain told AP the mishap took place at an Apple Store, explaining, "I was, like, walking by, I was like, 'Oh, that's Ron Howard.' And then my friend was with me (and) said he turned to someone, he goes, 'I think I just saw Bryce.' We look so much alike."
Bryce confirmed that the story was "legit" in an interview with Entertainment Tonight, saying her dad "was, like, shook. He really was."
"At first he was like, 'You really look so much alike,' " she said. "And I mean, obviously, I'm incredibly flattered, so it's great."
Neither celeb was upset when a social media user thought Witherspoon was Underwood while eating at a barbecue place in Nashville last summer.
"To the woman in the parking lot who just asked me if I was Carrie Underwood," the Legally Blonde star tweeted, "You officially made my day."
The Grammy winner quickly responded, "YOUR day?!?!?!?! That lady just made my whole life!"
"He's way better-looking than I was," Ruffalo said on the Tonight Show in March 2019. "Are you kidding me? I wish I looked like that, I swear to God."
People have told me that we look alike," Meyers said on Late Night With Seth Meyers in June 2018. As Grant said, "I know."
"I hope that I become half the woman she is," the actress said about George Clooney's wife, an international human rights lawyer, in an interview with Extra in 2015. "She's so accomplished and it's so thrilling to look at someone and be like, 'Wow. You really are making the world a better place.'"
Harry Potter and Frodo are well aware fans constantly confuse them, addressing their look-alike status in a joint interview with Empire magazine.
"Though we are both short, pale, blue-eyed and brown-haired, I would say we don't actually look alike," Radcliffe said. "But the idea of us is exactly the same."
The Harry Potter star was once even asked to autograph a photo of Wood while in Japan, with the seeker not realizing he was not the Lord of the Rings lead.
"So the quickest way to deal with it was to just write, 'I am not Elijah Wood, signed Daniel Radcliffe' and then hope someone translated that for him later," Radcliffe explained.
The actresses, who starred together in Nocturnal Animals, are aware of the comparison. In 2016, Fisher said on NBC's Today show that she once cut and pasted Adams' face over hers for her family's holiday card.
