Khloe Kardashian sat "slapping" Tristan Thompson during an awkward romantic gesture

Speaking on her Khloe in Wonder Land podcast, she said: "There was one time I was serenaded, and it was I think just a random day because I wasn't expecting it. This was years ago. Tatum wasn't born. Yeah, it was just True...

"Giveon wasn't who he was now. And he is just singing. I remember I hated Tristan and I was like, 'Why are you doing this?' And Giveon is pouring his heart out. And Tristan's trying to sit next to me and I'm like, slapping him, and poor Giveon is still singing. It was mortifying."

The 41-year-old star felt so awkward about the moment, she urged their daughter to join them outside to help relieve the tension.

She recalled: "I was like, 'God, this guy is such a great singer. I love this guy.' And I remember going inside to get True because I was like, 'I just need like a third person to get [away from] Tristan.'

"I was so annoyed with Tristan."

But the Good American founder can now see the funny side of what happened and praised Giveon for his professionalism.

She said: "It was so funny. Until this day, when I see Giveon he'll be like, 'Remember? If I could sing live for you two while you guys were fighting, [anything's possible].'

"Like, Giveon was so professional. He was so great. He didn't break his song at all. He's amazing, I love him.

"But how awkward for him? Poor guy, I love you, Giveon."

Despite Khloe and Tristan splitting shortly after Maralee Nichols gave birth to the basketball star's son Theo, now four, they have retained a good relationship for the sake of their children.

Khloe previously said on her podcast: "What I find so funny is that people are always like, 'How do you let Tristan back in?'

"And I'm like, 'Well, Tristan is not back in.' He's just the father of my kids, so he's going to be around his kids and I'm really grateful that he is.

"I love that he has a great relationship with his kids. That's a beautiful blessing and I'm never going to get in the way of that. I think it's so important for that relationship to maintain and be as strong as possible."
