People Editorial Guidelines Published on April 11, 2018 08:43 AM Share Tweet Pin Email Khloé Kardashian‘s famous family had their reservations about her boyfriend Tristan Thompson from the start, sources tell PEOPLE. The 27-year-old NBA star was allegedly videotaped getting close to an unidentified woman on Saturday in a New York City lounge — while Kardashian is nine months pregnant with the couple’s first child, a baby girl. (Thompson also shares a 16-month-old son, Prince Oliver, with ex-girlfriend Jordan Craig.) But the Kardashians were always a little hesitant about Thompson, and worried he wasn’t a good match. “When Khloé first started dating Tristan, her family questioned if it was a good idea. There were several concerns, including that he is another basketball player and also that his ex was pregnant,” a source tells PEOPLE. “It took a while for the family to accept Tristan. They were worried that Khloé would end up heartbroken.” The insider adds, “Being on the road as an athlete, you face many temptations. But Tristan always assured Khloé’s family that he was totally committed to Khloé. Khloé thinks the world of Tristan.” Jerritt Clark Tristan Thompson and Khloe Kardashian Another source tells PEOPLE that the reality stars didn’t realize how deceptive Thompson could allegedly be. “They are heartbroken for Khloé,” the second source says.

A man who has been identified as the athlete was seen speaking closely with a brunette in photos and footage published by the Daily Mail and TMZ.
