Kim Kardashian is filling a blank space on Ivanka Trump's Instagram.

In fact, the Kardashians star left well wishes for the former White House advisor's 13-year-old daughter Arabella when the teen celebrated her birthday with a cake modeled after the one from Taylor Swift's "Blank Space" music video.

After Ivanka shared photos of the Swiftie party on Instagram, Kim commented on July 17, "Happy Birthday Arabella."

Ivanka—the daughter of former President Donald Trump—posted a pic of Arabella smiling in front of a white, heart-shaped confection that oozed out red syrup resembling blood, with the icing baring the 1989 lyrics, "Boys only want love if it's torture."

The 42-year-old captioned one shot, "Best cake for my favorite Swiftie."

"Arabella, you inspire and amaze me every day," Ivanka added in the post's caption. "You are a remarkable young woman and my heart overflows with love for you. Happy Birthday!"

And while Kim—who also liked the post—has no bad blood with Ivanka, she does have history with Taylor, who she fell out with in 2016 after leaking a phone call between the Grammy winner and then-husband Kanye West.

"You have a fully manufactured frame job, in an illegally recorded phone call, which Kim Kardashian edited and then put out to say to everyone that I was a liar," Taylor recounted to Time last year. "That took me down psychologically to a place I've never been before." 

She continued, "I moved to a foreign country. I didn't leave a rental house for a year. I was afraid to get on phone calls. I pushed away most people in my life because I didn't trust anyone anymore. I went down really, really hard."

Their longstanding feud was rehashed in April when the Taylor released "thanK you aIMee," an allegorical song about confronting a bully.

"All that time you were throwing punches," she sang on the Tortured Poets Department tune, "I was building something / And I couldn't wait to show you it was real."

Kim has not addressed the apparent diss track, though she's said in the past that she is a fan of Taylor's music.

“I really like a lot of her songs," Kim told the Honestly podcast in 2021. "They're all super cute and catchy."

In a bold move, Chloë commented directly on the reality star's NSFW photos in 2016, telling the mom, "I truly hope you realize how important setting goals are for young women, teaching them we have so much more to offer than just our bodies."

Clearly, the advice wasn't appreciated, with Kim replying, "Let's all welcome @ChloeGMoretz to twitter, since no one knows who she is...your nylon cover is cute boo."

Since then, relations between the two have been icy. Luckily, Chloë nabbed herself a KKW perfume since she was on the haters list.

Where to begin? Besides the incident at the 2009 VMAs, people can recall the infamous feud that ignited between Kanye West and Taylor after the latter was referred to as a b---h in the rapper's 2016 song "Famous." Taylor released a statement saying she wasn't aware of the lyric "that b----h," but Kim was quick to defend her then-husband and shared an edited video of the singer talking on the phone with West.

Since then, there has been nothing but bad blood between the former couple and the "Karma" artist.

In fact, many Swifties believe Taylor's Tortured Poets Department track "thanK you aIMee" is about her longstanding feud with the Kardashians star.

Again, the Keeping Up With the Kardashians star was criticized for her nude selfie, but this time it was from Pink. In a subtle shade, the singer tweeted in 2016, "Shout out to all of the women, across the world, using their brains, their strength, their work ethic, their talent, their ‘magic' that they were born with, that only they possess. It may not ever bring you as much ‘attention' or bank notes as using your body, your sex, your tits and asses, but women like you don't need that kind of 'attention.'"

Kim later wrote an open message on her app, saying, "In all seriousness, I never understand why people get so bothered by what other people choose to do with their lives. I don't do drugs, I hardly drink, I've never committed a crime—and yet I'm a bad role model for being proud of my body?"

Wendy really stirred the pot in 2018 when she questioned the happiness in Kim's marriage. "Kim, you know what? It's clear that Kanye has nothing for you except dribble and feeble conversation," the talk show host said at the time. "It is clear that Kanye does not pay attention to you. It's clear to me that you are desperate, desperately trying to stay in the spotlight."

Neither Kim or Kanye—who broke up in 2021—responded to the shade, but Wendy was among the haters gifted KKW fragrances.

It was the tweet heard across the world. Bette tweeted to her followers in 2016, "Kim Kardashian tweeted a nude selfie today. If Kim wants us to see a part of her we've never seen, she's gonna have to swallow the camera."

And in an epic two-part clap back, Kim tweeted, "hey @BetteMidler I know it's past your bedtime but if you're still up and reading this send nudes #justkidding."

In a reference to Kanye's tweets about being in debt, Piers ttoom a jab at Kim's nude selfie in 2016, writing, "I know the old man's $50 million in debt, Kim - but this is absurd. Want me to buy you some clothes?"

In response, Kim fired back, "hey @piersmorgan never offer to buy a married woman clothes. That's on some Ashley Madison type s--t #forresearch."
