Welcome back, girl … or do we mean girls? Former Olympic gymnast McKayla Maroney took a month-long hiatus from social media after getting into a “pretty intense car accident.” But when she returned to Instagram last week, the athlete-turned-selfie enthusiast showed off what appeared to be much larger breasts.

McKayla, 21, shared a series of pics of herself wearing a low-cut top, which showed off her (new?) ample cleavage. “Yours truly,” she captioned the post. It wasn’t long before the Fierce Five alum’s fans flooded her comments section with questions about her seemingly boosted bust.

“Girl quit with the surgery. Only you could go from the Olympics to the HOE-lympics,” one wrote, while another commented, “Wait did you really get a boob job? U really didn’t need one.” Some of McKayla’s followers even suggested that her car crash story was made up so she could recover from plastic surgery in private.

“Ohhhh ‘car accident.’ Must be the new code name for ‘boob job,’” quipped one fan. Another follower even asked McKayla if it’s harder to tumble with breast implants. “Question. How are you supposed to do gymnastics with those new additions?”

Regardless of speculation that McKayla went under the knife, many of her fans did have nice things to say about her hot new look. “OMG you are absolutely stunning. Gorgeous gorgeous pic,” one wrote. Added another, “Honestly you are the most flawless person to ever live. And your boobs aren’t so bad either.”

This isn’t the first time McKayla has been hit with rumors of cosmetic enhancements. Last summer, the gold medalist — whose “unimpressed” face went viral five years ago at the London Olympics — told Seventeen that despite showcasing a plumper pout on Instagram, she hasn’t gotten lip injections.

“I literally have not done anything to my face,” she told the publication. “Growing up in the social media world, it’s tough. Your face changes, you get older, your face fills out, and you fall into liking makeup and different stuff like that. … Makeup and a camera can really make you look like a different person.”
