Back to work! New mom Khloe Kardashian was back to work at her Good American denim offices, on Friday -- after telling fans she was nervous about leaving baby True all day to resumer her duties as CEO of the company.

But Khloe looked happy to be back at the office, smiling and hugging co-workers as she entered. And let's be clear -- this is no suit-and-tie place ... Khloe wasn't in a pencil skirt and heels. No, this hot mama was in head-to-toe Spandex and Yeezys, looking like she was headed to the gym!

Her black catsuit showed off her amazing weight loss since giving birth to her daughter just less than three months ago. Kloe recently commented on a bikini pic her sis Kendall posted of her, saying it was deceiving and her body really isn't that great. But come on, Khloe! Give yourself some credit - you look AMAZING!
