The Dallas Mavericks game was the place to be Friday night -- especially for the jaw-dropping sight of LeAnn Rimes chowing down!

The super-skinny country singer, who grew up in Texas, was spotted putting away an entire hotdog.

A shot of her eating even made it to the JumboTron during the game.

Also in the crowd was Khloe Kardashian, cheering on hubby Lamar Odom who was traded from the Lakers to the Mavericks at the start of the season.

The reality star was joined by her brother Rob, and her stepkids Destiny, 14 and Lamar Jr., 9, and the family show of support seemed to help Lamar.  He had one of his best games since joining the Mavs, scoring 19 points.
