Khloé Kardashian and Tristan Thompson are celebrating love and basketball.

An NBA All-Star Weekend event doubled as date night for the couple — who are currently expecting their first child, a baby boy — this weekend. Stepping out together, the pair hit Rich Paul’s Klutch Sports Group’s annual The Game Is Every-Thing dinner party in Los Angeles, California, on Saturday.

Kardashian, 33, and Thompson posed together for photos, with the 26-year-old athlete smiling as he placed his hand on his girlfriend’s growing belly.

The reality star wore an all-black ensemble, a midi dress and jacket, for the dinner party, where guests feasted on kale and apple salads, tandoori spiced chicken, sherry glazed Atlantic salmon and filet mignon. For dessert, “Les, Nye” doughnuts satisfied every sweet tooth.

Kardashian gave a shout out to her man in a Valentine’s Day post on Instagram earlier this week, sharing a photo of the couple in front of red and white balloons that spelled out “I U.”

” ‘When a woman is loved correctly, she becomes ten times the woman she was before’ Thank you my love ,” she wrote.

In a post shared on her website and app, Wednesday, Khloé revealed the couple spent Valentine’s Day in Los Angeles.

“We’re both not very needy when it comes to this kind of stuff, so we’re just going to go to my mom’s and have a couples’ dinner with my family,” she said. “Cute, right? She’s having a chef cook for us, which will be a fun little luxury.”
