Denise Richards and Charlie Sheen’s daughter accuses sister of bizarre love triangle with her ex

Denise Richards and Charlie Sheen's daughter Sami has accused her sister of secretly hooking up with her ex-boyfriend.

The celebrity tea is piping hot - and very public.

For those who need a reminder, Charlie and Denise tied the knot in 2002, before welcoming daughter Sami in 2004 and their second daughter, Lola, in 2005.

The pair parted ways in 2006 and have co-parented their children ever since, who are now 21 and 20 respectively.

Anyone with sisters will know that it's a sibling relationship that isn't exactly smooth sailing, and you're bound to fall out every now and then. However, this may take the cake for the wildest sister drama we've seen in a while.

On Tuesday (January 13), Sami took to TikTok, where she boasts 273,000 followers, to accuse her sister of going behind her back with her ex-boyfriend.

Alongside a video of her looking shocked, she penned: "Imagine finding out your sister and ex-boyfriend have been seeing each other behind your back this whole time."

The video has already been seen by 3.1 million people and racked up over 3,000 comments.

One stunned fan questioned in the comments: "Nauuuuuuurrrr how did you find out," to which Sami responded: "Went through his phone and saw over 300 deleted texts between them."

Someone else asked: "Weren't they friends before you two got together?" and Sami replied: "Over 3 years ago."

Shortly after the bombshell dropped, Lola issued her own response in a TikTok video on Wednesday (January 14), where she categorically denied the claims.

As per PEOPLE Magazine, her statement read: "I am never one to defend myself against my sister anymore because I genuinely don't care. But I couldn't let this one slide.

"This is not true at all. I am single, I am not talking to anyone, and I'm definitely not dating her ex boyfriend."

She branded the shock claim as 'unbelievable' before laying out her side of the story.

The 20-year-old wrote: "Not that this is anyone business, but the truth is my mom hired [Sami's] ex boyfriend to take care of my moms dogs and basically clean our whole house, so he has been working for her almost everyday.

"I was living with roommates, and had to move back home for the meantime until I move into another place. I was absolutely not speaking to her ex-boyfriend, but then my mom allowed him to move into our house, across the hall from me."

She clarified that while she's had a few conversations with Sami's ex-boyfriend because they're living under the same roof, she 'would absolutely NEVER do anything with my sisters ex boyfriend'.

Adding that it's hard to 'completely ignore someone who is in the same home as me now'.

Lola signed off with: "And we have completely different types in men. This is not a situation I want to be in at all, but I truly have no control until God provides a different place for me to move into.

"My sister has always posted things about me online to get people to hate on me, with absolutely no context at all.

"I have absolutely not been seeing her ex boyfriend. That is a complete lie. You can believe whatever you want because I really don't know any of you personally, and only the people closest to me know that this is not true at all.

"My sister has always posted things about me online to get people to hate on me, with absolutely no context at all."

Tyla has contacted reps for Sami and Lola for comment.
