Los Angeles, California - Khloé Kardashian caught some flack from fans after she was seen with her ex Tristan Thompson, who did her dirty.

After relieving Tristan's cheating and paternity scandal on the finale of The Kardashians, which aired last week, Khloé was once again trending on Twitter - and yes, it had to do with her ex.

On Sunday, the former couple were seen with their daughter True, where they reportedly joined the Kardashain-Jenner clan for a Father’s Day lunch.

In one snap shared by Twitter users, the NBA star is seen cozying up to the reality star, and his arm was placed around her.

Another pic showed the family taking a stroll, with True holding on to her dad.

Even the Kardashian family matriarch Kris Jenner was pictured chatting with Tristan while enjoying the LA sunshine.

Yet, the seemingly sweet family moments were heavily criticized by fans for a plethora of reasons - and Khloé herself has responded to the madness.

It appears that despite the two's most recent split over Tristan's numerous cheating scandals, Khloé is trying her best to remain amicable with the father of her daughter.

While the Father's Day outing seemed innocent and based around the Sacramento Kings player spending time with True, many fans still called Khloé and Tristan out. Particularly since it's been reported that Tristan hasn't even met his youngest son Theo, whom he at first denied fathering with Maralee Nichols.

"Did Tristan Thompson spend Father's day lunch with his other baby mamas?? So Khloé Kardashian is happy to parade with this man because he is 'True's dad'.... Girl that's your man, own up to it lmao," one user wrote, slamming Khloé.

The Good American owner responded to the criticism under a reposted snap of the outing by a fan on Instagram.

"Hummmm Very calculated of the paparazzi to not release photos of my other sisters and the fathers of their children Kim/Kanye Kylie/Trav," Khloé wrote.

There were some fans who seemed to have the tea on the situation, and came to Khloé's defense.

"True had her first dance recital today and [Tristan] went. Then after she dropped true off with him at the parking lot and drove off ALONE? She gave him a one arm hug cos that’s the father of the child? He may be a BS partner, but he’s a decent father according to her so they’re cool," a fan tweeted.

Regardless of where everyone stands, it should be noted that Khloé didn't give the basketball player a Father's Day shoutout on any of her social media platforms.

Plus, Tristan putting his arm around Khloé is hardly enough to suggest she's giving him a second chance.

Perhaps it's time for everyone to worry less about how the reality star co-parents with the athlete, and more about her moving onwards and upwards.
