The show must go on!
Not that we ever doubted that, because what better way to forget your relationship drama than by filming for your lucrative and wildly successful show.
And it helps to have your sisters there with you!
We bet filming Keeping Up With The Kardashians at Hugo's in Calabasas was therapeutic for Kourtney Kardashian, who looked cheerful as she hung out with sisters Kim Kardashian West and Khloe Kardashian on Tuesday.

Kourt followed in Kimmy's rock 'n' roll t-shirt loving footsteps by wearing a faded The Police tank with her ripped jeans.
Meanwhile, Khloe showed off her legs in a pair of very short shorts while Kim was the most glamorous of them all in a gray dress and Haider Ackermann sheer duster.
Kanye West's wife also dressed up extra sexy for dinner at Giorgio Baldi with her husband later that night after a hard day's work on set.
The pregnant reality star was all about the cleavage in a low-cut, semi-sheer black dress.
