and Khloé Kardashian
shared lots of sisterly bonding
– and reality show filming – in Dallas. The two started their day with lunch at Palomino downtown with cameras following them. "They wanted it to be kind of low-key," a source at the restaurant tells us.
After their meal, they headed to Stanley Korshak
, an upscale department store, for some shopping. A source at the store called their visit a "fun surprise. They're lovely, and we really enjoyed having them in the store."
Next up: a stop at the Dallas World Aquarium, where Khloé posed near the leopard exhibit.
The sister ended their evening at the Dallas Mavericks game
, where Lamar Odom scored a season high 15 points against the Phoenix Suns. – Darla Atlas
