This Kardashian is keeping up with her work out regimen!

Khloé Kardashian was camera ready and eager to show off her thin body when she attended a SoulCycle class in Santa Monica, Calif., Monday.

“She arrived for the 7:30 p.m. class with E! cameras in tow,” a fellow cycler tells Life & Style.

“She was all glammed up — her hair and makeup were done.”

The 29-year-old’s hard work at the gym is definitely paying off — and strangers are taking notice.

“She looked really amazing and skinny,” the eyewitness says.

Khloé, who recently nabbed Justin Bieber’s Calabasas, Calif., mansion, rocked an all-black ensemble with a flannel tied around her waist, which accentuated her shrinking mid-section.

Since shedding 30 pounds, the reality star has been taking every opportunity to flaunt her fit physique.

“I’m feeling good,” she told Cosmopolitan earlier this year. “I’ve worked very hard on my body, so I think now I can sex it up a little! My 2014 mission is to wear a crop top with jeans. I’ve never done that, so it has to happen one day.”

The 5-foot-10 starlet, who has struggled with weight her entire life, has been focused on maintaining her new healthy lifestyle.

“I don’t deprive myself of food,” she said. “It’s everything in moderation, so if I need something sweet I’ll have a bite or two.”

It’s also been a good distraction for her during a very tough time — she filed for divorce from her husband Lamar Odom in December.

On Sunday night’s mid-season finale of Keeping Up With the Kardashians, Kim and Kourtney and Khloé’s pal Malika Haqq held an intervention to convince her to divorce the former NBA star.

“It just sucks when you’ve given so much and you realize it still wasn’t good enough for someone,” Khloé says in the episode. “You can’t help but take it personal.”

It’s later revealed she filed the papers.

“It just sucks. I definitely feel guilty,” she says. “It’s definitely f*cked up – it’s not a good feeling at all.”
