Time to get moving! On April 21, model Amelia Hamlin was spotted going to a Forma Pilates class — the very same one Kaia Gerber attends.
The star, who was wearing a matching monochrome set, has been attached at the hip with boyfriend Scott Disick, but she was flying solo for her workout.

The young model donned a matching sweatshirt and leggings, a sporty pair of '90s style sunglasses and huge black tote while waiting by the entrance.
Coincidentally, a source told E! that Disick's ex-girlfriend Sofia Richie was also set to take the exercise class!
"It was a very awkward situation for Sofia and she didn't know Amelia was also going to be taking class at the same time," the source spilled. "She just wanted to avoid the situation all together so that's why she left."
The brunette beauty kept to the brown theme with a dark pair of ankles socks and beige slide sandals from Kanye West's Yeezy line.
Hamlin started seeing Disick last fall, and though it may have started out as a fun fling, an insider told PEOPLE things are turning "serious."
"She grew up in the industry and knows how all this works," explained the insider. "It's a different type of maturity, and they really don't feel the age difference. He's been telling friends how much she means to him and how into her he is."
The star let her ombre locks down while heading to the Pilates class.
Earlier this month, Hamlin and her beau vacationed in Miami, Fla., where they were seen shopping for jewelry. Notably less expensive, she also donned a beaded bracelet with Scott's first name on it.
During her trip with the reality star, the duo strolled the beach, caught up with friends and took a dip in the pool alongside Hamlin's sister, Delilah.
The star held onto her iPhone while waiting around on the sidewalk.
Despite her and Disick's 18-year age gap, her mom, reality star Lisa Rinna, seems to approve of the romance, as she poked fun at the father-of-three's "bucket hat" earlier this month.
