Millie Bobby Brown 'Looks 40' Cycling Indoors In A G-String

Millie Bobby Brown received both praise and criticism as she upped her workout game in a sporty-themed Instagram share this Spring. In March, the actress posed on an indoor bike as he channeled '80s gym vibes, with the photo promoting her 2024-founded Florence by Mills Fashion brand. Displaying her fit figure in a cheeky bodysuit and sneakers, Millie showed off her label's athleisurewear range, but the comments section proved rocky as Millie was both trashed for her skimpy look and accused of looking nearly twice her age. One user gained likes for saying that the 21-year-old "looks 40."

Scroll for the photo. Striking a pose on a lightweight gym bike as she highlighted her toned legs and sculpted rear, Millie made a case for the thong look, rocking a gray one-piece that clung to her every curve.

The British sensation, who is running her clothing brand alongside her Florence by Mills cosmetics company, teased her abs in her butt-baring look, opting for an unusual bodysuit that fed into a hoodie up top.

Adding knee-high white socks with pops of color, Millie nailed her throwback vibe, completing her sporty look with a baseball cap. The Stranger Things star also added girly touches from a pink baseball cap as she posed with her backside lifted above her bike's seat. In a caption, she and Florence by Mills Fashion wrote: "Disclaimer: no workouts were done in the making of this collection."

The post may have netted over 3 million likes, but Millie still fell under fire. "She is not hot!" one fan said, gaining over 50 likes. "Yeep, looking like a 40-year-old woman hitting the gym after a divorce!!" was a reply netting over 70 likes.

Another user said that Millie looked "38," with a further fan claiming that she was "trying too hard." Fortunately, Millie Bobby Brown didn't only gain negative replies, with multiple users saying that she wasn't a 10, but an "eleven." Millie has suffered her fair share of "looking 40" comments this year, notably as a result of her blonde bombshell era, which debuted earlier this year.

"Beautiful, but looks so much older," one fan replied. "I just don't understand why she looks older than she actually is," another said. Millie has repeatedly defended her decisions to dress and glam up the way she likes, also outlining that it's the fans who have a problem with her growing up since her early, pre-teen days on Stranger Things.

This March photo offered another reminder of Millie Bobby Brown's new makeover as she stunned in a sparkly burgundy dress while going strapless. "A STUNNING QUEEN," one fan replied as the share earned over 2 million likes. Millie also snagged a celebrity like from socialite Paris Hilton.
