The 25-year-old basketball player is so worried about his beau following the attack on her sister Kim Kardashian West in Paris earlier this week, that he's called for extra protection when she comes to see his Cleveland Cavaliers games.

A source told HollywoodLife.com: "He wants her to be at every home game that she can possibly attend and has asked Cavs executives for extra security when she's in the building.

"No disrespect to LeBron [James], but Tristan wants Khloé to be more protected at the arena than Savannah [James]!"

Tristan's worries come after Khloé's 35-year-old sister went through a horrific ordeal on Monday (03.10.16) when five thieves dressed as policemen robbed her at gunpoint in her apartment in Paris, during which they tied her hands with plastic handcuffs, duct taped her, and stole more than $10 million worth of jewels.

Now, the Cleveland Cavaliers forward wants to make sure that never happens to Khloe, 32, by ensuring she is "protected to the hilt".

The source added: "Khloe's an international phenomenon, a celebrity with a face that's as recognised around the globe like First Lady Michelle Obama.

"Tristan has only just realised the magnitude of who Khloe is and wants her protected to the hilt when she takes time out of her busy schedule to watch him play."

Speculation about the new couple started circulating last month, with sources saying they were taking it "day by day", but with Tristan's dedication to keeping Khloe safe, they might be more serious than they're letting on.

A source said previously: "They're taking it slow, day by day, but are having so much fun together. He's the nicest, sweetest guy. He comes from a very strong family and has a tight circle of close friends. He really isn't into the 'celeb scene' and does his own thing."
