The "All of Me" singer shared the news in a tweet on Monday afternoon

John Legend is diving in!

The “All of Me” singer, 40, revealed in a tweet on Monday afternoon that he was taking swim lessons for the first time since he was 5 years old.

Despite the unusually late start, Legend said he’s actually one step ahead of his father, Ronald Stephens, who started to learn when he was in his 60s.

“I can’t really swim. Today I took my first swim lesson since I was like 5,” Legend tweeted. “My dad learned in his 60’s so I feel like I’m ahead of schedule.”

Immediately after posting the revelation, fans shared their thoughts — some were in disbelief, while others supported the dad-of-two.

“Are you learning with your kids?” wrote one fan, to which Legend revealed that his 2-year-old daughter Luna Simone and 8-month-old son Miles Theodore were already taking lessons. “They already started months ago!” he responded.

Some fans thanked Legend for sharing his story, as they were also going through a similar experience.

“I learned when I turned 30 – was tired of being worried about it and avoiding water – You’ll do great!!!” wrote a fan.

“Good for you! The life you save may be your own, your child’s, a perfect stranger’s even! It’s NEVER too late,” added another person.

“I’m taking swim lessons this spring. Thanks for sharing your story. I no longer feel ashamed,” explained a Twitter user.

Even the American Red Cross commended Legend for learning a crucial skill. “Congrats! Learning about water safety and how to swim are important at any age. #BetterLateThanNever” they wrote.

Others, meanwhile, poked fun at the singer and his 2013 hit song “All of Me,” which says in the lyrics: “My head’s under water, but I’m breathing fine/You’re crazy and I’m out of my mind.”

“So what happened when your head was under water? Did you breathe fine? Was it all a lie?!” asked a fan.

“All. Lies. Hahaha,” Legend jokingly wrote back.

At one point, fans even began to question Legend and Chrissy Teigen‘s parenting and pool safety — asking what would happen if Legend or their kids accidentally fell into the pool — to which Teigen quickly defended her husband and snapped back.

“Not trying to disrespect U or your kids. Just wanted to put out there for general knowledge about pools, children, and safety precautions in response to someone commenting @ John slipping into pool,” clarified a fan afterward.

“ok I’m sorry. misunderstood but get very defensive when people question our kid’s safety,” Teigen, 33, wrote back.

Legend and Teigen rarely ever hold back when it comes to candidly talking about raising their kids, but if social media users begin attacking their parenting, that’s when Teigen’s protective motherly instincts come out.

“You can call me whatever you want. You can call me ugly, you can say my forehead is big, you can say my dress is hideous, but once you start talking about my food and my child that’s when I get really crazy,” Teigen previously told Parents magazine.

Besides speaking openly about the challenges of breastfeeding, nailing the perfect family photo with two young children, and why she frequently posts “real mom s—” online, the Lip Sync Battle host has also revealed that Legend’s worst parenting trait is the fact that he’s a pushover.

“He will say no and then if [Luna] asks one more time, it’s a yes,” Teigen admitted to BUILD Series. “He’s a bit of a pushover with Luna. I think it’s because they look so much alike and he’s like, ‘Okay, you beautiful being. Anything you want.'”

“He needs to learn to say no because I’m the tough guy,” she continued. “It’s always a thing in any household, there’s always one.”

Though Legend may have trouble disciplining Luna — whom Teigen said is very spoiled — and eventually Miles, there are skills that he continues to impress his wife with.

“He’s also insanely patient,” Teigen said of her husband of five years. “He’s amazing at diaper changing still.”

Added the Cravings author: “He gives them so much attention no matter what’s going on in his life or my life or work-wise. They never feel like they’re like second to work and I think he’s really great with that.”
