Tristan Thompson All Smiles Leaving Cleveland and Khloe for Playoffs

Tristan Thomson's temporarily out of the dog house, physically anyway, and he couldn't look happier.

Tristan was grinning from ear-to-ear as he boarded the Cleveland Cavaliers team plane Thursday, heading to Indiana for Game 3 of their playoff series with the Pacers.

He could be smiling 'cause he's a new dad, or because the Cavs tied the series 1-1 last night. Or maybe he's just happy to get outta Dodge after getting busted cheating.

Considering he hasn't been playing much, we'll go with door #3. As we've reported, his relationship with Khloe Kardashian is in ruins at the moment, and after her family left town there's no buffer between them.
