Khloe Kardashian 'worries about curves'
Khloé Kardashian apparently worries she's bigger than her pregnant sister Kim.
The reality TV star is known for her curves, but is reportedly concerned her figure is more voluptuous than her sibling's.
Kim has stayed trim since announcing she was expecting her first child with Kanye West in December and it seems Khloé has also decided to step up her fitness plan.
"Khloé loves her curves, but wants to look more toned, so she's working out every day, doing an hour of cardio. She's aiming to lose 14 pounds," a source told British magazine Closer.
"Khloé's joked she's bigger than Kim now, who's pregnant! She laughs about it, but she's self-conscious when she sees photos of herself with Kim."
Kim has been very vocal about her fitness regime, keeping fans up to date via her blog and Twitter page.
Whereas she looks great, those close to her are apparently worried she's working too hard.
"She's still hitting the gym regularly - often twice a day - as well as taking on more and more work to keep active. Everyone around her is concerned she's doing too much when she should be taking it easy," a source recently told British magazine Look.
Third Kardashian sister Kourtney has bounced back into shape since giving birth to her second child, Penelope, last year.
