Britney Spears isn't the only member of her family with a rock-hard gym body. The "Toxic" singer's little sister Jamie Lynn seems to have inherited the 38-year-old's killer legs, with a new workout video showing just this.

Jamie has been making headlines recently for opening up about an ATV accident that nearly killed her eldest daughter Maddie back in 2017, but the star's video today showed her with youngest daughter Ivey.

It was an adorable mommy-daughter bonding moment, a reminder that family factors hugely into Jamie Lynn's life, and fans of the star's steely legs got a treat.

The video showed Jamie Lynn and daughter Ivey in a gym with wide open spaces. The "Zoey 101" alum was in full workout mode, doing reps with dumbbells as she stood alongside her toddler.

Jamie Lynn was looking incredible. The actress and singer was wearing a teeny tiny pair of shorts flaunting her super-muscly legs, pairing the lowers with a baggy t-shirt and white baseball cap.

Little Ivey didn't seem quite old enough to realize what was going on, but she too had a mini set of dumbbells (and semi joined in with mom after a little encouragement).

Spears took to her caption to mention her youngest daughter, alongside a bit of a joke over how little this infant weighs.

"My workout buddy barely even does the workouts, but she still only weighs 25lbs.. so not fair. ???," she wrote.

Fans were loving it.

"Beautiful," one said.

"She is so adorable beeings she sees you from little one will make her want to work out as she gets older," another wrote.

"Aaaaaw she’s so cute ??❤️" was another comment.

The update also proved popular overall, racking up over 13,500 views in just 35 minutes.

Jamie Lynn bravely took to Instagram on Monday to share the horror of an ATV accident that nearly killed 11-year-old daughter Maddie this time three years ago. She posted a photo of Maddie in the hospital, also adding her thoughts.

"3 years ago today, Super Bowl Sunday fell on February 5th, and I’ll never forget that, because it was the day my whole world stopped. It started like most Sundays, going to church, visiting family, to suddenly trying to save my daughter's life, to them taking her away, to us believing we had lost her forever, and it literally felt like the world stood still around me," she began.

The accident saw Maddie's ATV flip over, leaving this child near death. Jamie Lynn continued to say that she'd never spoken about the event in this much detail.

"I have never spoken fully in detail about that day, and the events that followed, but what I will share is that God blessed us with a true miracle. Maddie not only stayed here with us, but she made a full recovery," she added.

Also thanking fans for their prayers at the time, Jamie Lynn concluded with gratitude and a message of hope.

"Let’s all be thankful for the tiny miracles in our lives everyday, that we may take for granted, because it could all change in a second. Thank y’all for always being there for me and my family, we appreciate you and love you so much. #MiracleAnniversary," she wrote.
