Kourtney Kardashian & Travis Barker Show Khloé Kardashian Support Amid Tristan Thompson Paternity Scandal

Khloé Kardashian gets flowers from Kourtney Kardashian and Travis Barker!

The Poosh founder, 42, and her rocker fiancé, 46, expressed their full support to the Good American co-founder, 37, by sending her roses. Khloé shared a picture on her Instagram Story and added a note thanking the couple.

"My cuties @travisbarker @kourtneykardash I love you ?" she wrote.

Khloé has had her heart broken once again by her baby daddy, Tristan Thompson, 30. The NBA star cheated and fathered another child with Maralee Nichols, 31, a personal trainer from Texas.

The baby is Tristan's third child following his alleged fling with Nichols. At first, the Sacramento Kings team player didn't acknowledge the baby, which led Nichols to file for child support. He is also dad to son Prince, 5, who he shares with ex Jordan Craig, 30.

According to the documents obtained by DailyMail, the baby was conceived in Houston, Texas, during Tristan's 30th birthday bash in March. He was dating Khloé at the time, with whom he shares a three-year-old daughter named True.

Nichols moved to Los Angeles in the midst of their messy court battle. Apart from child support, she also wants him to reimburse the medical expenses and pregnancy-related costs.

After finding out the results of the paternity test, Thomspon took to Instagram and made a public apology to Khloé.

"Khloé, you don’t deserve this,” he wrote in a post. “You don’t deserve the heartache and humiliation I have caused you. You don’t deserve the way I have treated you over the years. My actions certainly have not lined up with the way I view you. I have the utmost respect and love for you. Regardless of what you may think. Again, I am so incredibly sorry."

Khloé has not commented on the issues personally, but a source close to the Kardashians revealed that she's "glad" that Tristan is taking full responsibility.

"Khloé is glad to see that he took responsibility for, and owned up to, being the father of Maralee’s son,” the insider told HollywoodLife. “It was the right thing to do, but Khloé wishes he would have left it at that. Khloé does not care about his apology because his words mean nothing to her anymore. She can’t trust him, and she will never be able to trust him again.”

Kourtney is not the only sibling who showed her sister some love. Kim Kardashian, 41, also stood by Khloé's side through these hard times.

The mother of four posted a lovely black-and-white family photo of the two siblings posing for the camera during a Sing 2 event on January 4. Khloé was seen carrying True, while Kim held daughter Chicago, 3, in her arms and standing behind his son Saint, 6, in the shot. The beauty mogul's eldest daughter North, 8, made an appearance in the following slide.

Longtime Kardashian family member Scott Disick, 38, also sent flowers to Khloé earlier last month, just days after the news of Tristan's infidelity came out.
