Jamie Lynn Spears' killer legs are back on the 'Gram. The 28-year-old sister to pop icon Britney Spears seems to have inherited her sister's genes when it comes to having rock-hard pins, with a brand new Instagram update from the "Zoey 101" alum appearing to prove just this.

Jamie Lynn updated her Instagram on Monday for a little leg flaunting and some top-up income. The star joins the swarm of celebrities promoting box-delivered products company FabFitFun – reality star Savannah Chrisley and actress Denise Richards join her.

Jamie's post showed three photos. While the middle one simply focused on the product being promoted, the first and last offered a fantastic view of the Nickelodeon star's super-fit body, not to mention those sensational legs.

Jamie was posing seated and in her home, flaunting her gym-honed pins in a tiny pair of Daisy Dukes paired with a knotted white-and-green shirt with leaf prints. The blonde smiled for the camera as she showcased the goods, also abiding by Instagram's required #ad.

Jamie took to her caption to announce her partner status with FabFitFun.

"#fabfitfunpartner Happy March! I just got my #fabfitfun Spring Box filled with all these amazing items that are perfect for this Spring season. I’ve been loving trying all these products, especially the Cal Pak packing cubes that have been an essential travel item for me! Use my code JLS10 and get $10 off your first @fabfitfun box! #ad," she wrote.

The update might have been a promo, but it nonetheless racked up likes from Jamie Lynn's followers – over 3,200 were clocked in 45 minutes.

Pay on Instagram directly correlates with following –the bigger the following, the higher the pay. Vox broke down the potential earnings.

"Influencers with up to 1 million followers can get $10,000 [per post], depending on the platform, and 1 million followers and up, you’re getting into territory where they can charge $100,000. Some can even get $250,000 for a post! Especially if the content is on Youtube and the influencer is in the gaming industry."

Jamie Lynn has 1.8 million Instagram followers.

Responses coming in to Jamie Lynn's post seemed far more focused on the upcoming Netflix face's killer body and cute style than her offerings, although the ad likely served its purpose.

"Well it seems to work, you seem to look younger and younger every year," a fan wrote.

"Wow body goals I need to get into running!? How long do you usually run for?" another asked.

Jamie recently made headlines for her workouts – a cute one with 2-year-old daughter Ivey saw mom and daughter be workout buddies, with Jamie Lynn also seen running in tiny shorts.

Jamie has yet to give away the secret to her legs.
