Nicole Richie and Khloe Kardashian were spotted with their ‘game face’ this morning (Jan 10) as they hit the gym together in Studio City, CA.

“Work time!!! I am trying a new workout today… I love switching it up.” Khloe tweeted, before stepping out.

Meanwhile, rumours are really swirling around Khloe, that she may be pregnant with first child.

A source tells Page Six that Khloe was hiding something under all that material during last week’s People’s Choice Awards. Khloe’s been “hiding a tell-tale bump behind flowing dresses and oversized handbags.”
