Paris Hilton is celebrating #ThrowbackThursday a few hours early.
But she isn't doing it via some memorable or funny photos from several years ago.
She's doing it by reigniting a decades-old feud with the one former celebrity who may be more irrelevant than she is these days.
Yes, Lindsay Lohan, we're talking about you.
The former A-Listers, both of whom have seen their Q-Rating drop more precipitously than Hilton's pants in her infamous amateur porn video, are evidently at odds once again as a result of something Paris wrote on Instagram.
This is all a little bit confusing and a whole lot random, but here we go...
A Paris Hilton fan account (yes, these actually exist!) on Instagram shared a montage of paparazzi videos of Lohan in the 2000s this week.
During her darkest period, of course, the ex-actress was involved prominently during this decade in many scandals and disagreements.
The first clip from the aforementioned video is from November of 2006; it features Lohan claiming that Hilton had hit her in the arm the night before at a friend's house and also poured a drink all over her.
Then, in the second section of footage, Lohan takes this statement back and says she loves Paris.
"Paris is my friend. Everyone lies about everything. She's a nice person...she never did that. She's a good girl," Lindsay tells photographers as she ducks into the car with Hilton behind the wheel in this snippet.
Then, there's a third segment of the video in which Lindsay seemingly calls Paris a "cunt," prior to immediately claiming she did no such thing,
(A certain President of the United States stand up and applaud Lindsay for her ability to tell fudge the truth, if you will.)
At some point, this video must have made its way into Hilton's feed because actually left a comment on it that reads:
Lohan and Hilton go back a VERY long way.
Lindsay allegedly dated Hilton's ex-boyfriend, Stavros Niarchos, about 12 years ago.
Lohan, meanwhile, once quipped that Paris is "very comfortable making videos," a clear reference to her sex tape.
Then, in 2013, Hilton's younger brother alleged that Lohan was actually behind a beating he took in Miami.
We haven't heard much about their relationship since then; nor much from either star since then, period.
However, Lohan recently went after Kim Kardashian, indicating that she's unafraid to stir things up with fellow celebrities just like she did in the old days.
Although she'd claim otherwise.
"I’m a normal, nice person. A good person. I don’t have any bad intentions. And my past has to stay in the past," Lohan explained in a new interview, adding:
"People have to just let go of it and stop bringing it up because it’s not - it’s gone. It’s dead. And that’s the most important thing to me."
Okay, fine. Fair enough.
But someone better pass that message along to Paris Hilton.
(At press time, Lohan had not responded to Hilton's liar diss.)
