Photos: Kourtney and Kim Kardashian Head To The Children's Museum

Kourtney Kardashian and her kids, Mason and Penelope, are spending some time in Miami this fall. Kourtney and her sister Kim Kardashian are filming their latest E! reality show, Kourtney and Kim Take Miami (formerly known as Khloe and Kourtney Take Miami). Khloe has scaled back her role in the spinoff as she has been busy with negotiations to become the new co-host of 'The X Factor'.

Yesterday the celebrity siblings were spotted heading to the Children's Museum in Miami, along with Sophie Pippen, daughter of Scottie and Larsa Pippen.
