Khloe Kardashian is a hands-on stepmom!

Khloe spent the weekend with hubby Lamar Odomo's kids -- Destiny and Lamar Jr. The reality star has spoken openly about wanting to get pregnant herself -- she seems to be flexing her maternal instinct muscles!

The foursome hung out in the sunshine and grabbed slushies before driving off in the $400,000 Rolls Royce that Khloe bought Lamar for the Lakers' championship win last year.

Check out all the pics of Khloe and the kids in our gallery below!
