Khloe Kardashian is dating Los Angeles Lakers star Lamar Odom.

The two were spotted leaving popular Beverly Hills restaurant STK hand-in-hand on Thursday night.

“They’re very, very happy. They’ve been together a few weeks, and are literally inseparable,” big sister Kim Kardashian told PEOPLE on Friday. “Khloe thinks he’s amazing and [he] makes her laugh and smile constantly.”

Khloe, 25, currently stars on the E! reality series Kourtney & Khloe Take Miami, with her pregnant eldest sister Kourtney Kardashian. Lamar, who has three children with a former girlfriend, recently signed a four-year, $30 million contract to stay with the Lakers.

This isn’t Khloe’s first high-profile relationship with a sports celeb. The reality personality previously dated Timberwolves guard Rashad McCants.
