It's fair to say that remaining faithful to his partners is something US basketball star and Khloe Kardashian's baby daddy, Tristan Thompson, is seemingly incapable of.
The 28-year-old is famous for being a cheater - he was reportedly in a relationship with Khloe while his ex-girlfriend Jordan Craig was pregnant with his son Prince, and was later revealed to have cheated on Khloe twice, once while she was pregnant with the couple's daughter True and again with her sister Kylie Jenner's best friend Jordyn Woods.
It's not secret that Khloe's fans - and any woman who understands the devastating pain of being cheated on - certainly aren't fans of Tristan.
He's caused Khloe a huge amount of pain, so much so that now the couple have officially split for good.
So when Tristan took to Instagram today to wish Khloe a happy 35th birthday in a loved-up post, you'll have to forgive us for not immediately gushing with hearts in our eyes over his supposedly sweet gesture.
Posting to his three million followers, Tristan wrote: "Happy birthday @khloekardashian. You are the most beautiful human I have ever met inside and out. Thank you for being an amazing mommy to our princess True. She is blessed to have someone like you to look up to. I wish you nothing but more success and sending you positive blessing your way. Enjoy your day Koko ❤️". "
Of course, Tristan has limited fans' ability to comment on his post, so all you'll find are 15 positive comments from friends and other celebs wishing Khloe a happy birthday.
In February, soon after the cheating allegations about Tristan and Jordyn emerged, Khloe and Tristan officially split, this time for good.
US Weekly confirmed the split, with a source quoted as saying: "They aren't speaking."
The breakup came after Khloe angrily took to Twitter and blamed 21-year-old Jordyn for the cheating scandal.
"Why are you lying @jordynwoods?? If you're going to try and save yourself by going public, INSTEAD OF CALLING ME PRIVATELY TO APOLOGIZE FIRST, at least be HONEST about your story. BTW, You ARE the reason my family broke up!" she tweeted.

In a series of subsequent tweets, Khloe later acknowledged that while Jordyn's action were terrible, she shouldn't place sole blame on her for what happened.
"Tristan is equally to blame but Tristan is the father of my child...Regardless of what he does to me I won't do that to my daughter. He has been addressing this situation PRIVATELY," Khloe tweeted.
"This has been an awful week & I know everyone is sick of hearing about it all (as am I). I'm a roller coaster of emotions & have said things I shouldn't have," she admitted.
"Honestly, Tristan cheating on me & humiliating me, wasn't such a shock as the first time ... What's been harder & more painful is being hurt by someone so close to me. Someone whom I love & treat like a little sister.
"But Jordyn is not to be blamed for the breakup of my family. This was Tristan's fault...I have to move on with my life & count my blessings, my family, my health, & my beautiful baby True."
