Kim Kardashian didn’t let an evening TV appearance stop her from working out last night.

The reality star, 33, went straight into a gruelling fitness session after getting dolled up for Jimmy Kimmel Live.

‘Late night workout after Kimmel,’ Kim told her Twitter followers.

‘I was tired but I’m so glad I pushed myself to workout! #WorkedOutInFullGlam #Gross‘

Kim had earlier looked very glamorous on the chat show and showed her originality by tearing up a designer frock to create a tiny top and pencil skirt.

‘Tonight’s look- #AllPinkEverything #DiorDressICutInto2Pieces #ManoloHeels #LorraineSchwartzJewels,’ the new mum captioned a picture on Instagram.

The slim-fitting Dior outfit certainly made the most of Kim’s ample cleavage and hourglass figure.

On Thursday Kim went for a more relaxed look when she went out shopping with fiancé Kanye West, 36, and seven-month-old baby North in Beverly Hills.

The TV star dressed down in a white top and skinny jeans and wore her hair in a messy bun as she pushed her daughter in a buggy.
