Woods, 21, is also a member of the Good American squad, representing Kardashian’s clothing brand.

Thompson, 27, was photographed partying in Los Angeles. last weekend without Kardashian, 34. A source tells PEOPLE that Thompson attended a house party Sunday and allegedly made out with another guest, though the source did not know if that person was Woods. The source says Kardashian heard about his behavior but doesn’t seem upset and is focusing on raising their daughter True, 10 months.“Khloé has acted like she is single for a while. She is focused on herself, her daughter and their life in L.A. She isn’t spending time with Tristan. She doesn’t act like she is planning a future with him. All because she can’t trust him,” the source explains. “She constantly hears rumors of inappropriate behavior when it comes to Tristan. She as recently as this weekend heard that he was being inappropriate.”Reps for Kardashian, Thompson and Woods did not immediately return PEOPLE’s requests for comment.

Kardashian’s best friend Malika Haaq commented “STRONG FACTS” on Hollywood Unlocked’s post, as captured by The Shade Room. Kardashian herself commented a string of emojis of someone yelling, and sister Kim Kardashian liked the Instagram.

Kardashian and Thompson haven’t been photographed together since Jan. 13, when they stepped out for dinner at Craig’s in West Hollywood following the Cavaliers’ game against the Los Angeles Lakers.
