Kim Kardashian, Calvin Harris pose for photo together

This will probably strike a sour note with Taylor Swift.


Kim Kardashian and Calvin Harris — who have both feuded with the pop star in recent weeks — posed for a photo together Saturday in Las Vegas.


The two stars were also pictured with pop star Jennifer Lopez and rapper French Montana, who uploaded the image to his Instagram page.


Kardashian, 35, is holding a cake in the photo, presumably for J. Lo, who celebrated her 47th birthday on Saturday. The "Keeping Up with The Kardashians" star was on hand for Lopez's performance in Sin City, while Harris was partying on the Strip, TMZ reports.


Both Harris and Kardashian have made headlines this month after firing shots at Swift in a pair of separate incidents.


Harris, 32, unleashed a fuming Twitter rant against his ex-girlfriend after she took credit for writing his smash hit "This Is What You Came For" less than two months after their breakup.


"Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage," he wrote in one tweet, after confirming Swift had indeed penned the song's lyrics.


Swift, who dated Harris for 15 months, is now seeing actor Tom Hiddleston.


Days later, Kardashian unveiled footage of Swift seeming to sign off on at least one lyric in Kanye West's song "Famous" - months after Swift's publicist said West had only called her for help promoting the song, not her approval.


In the conversation, Swift appears to give her OK to the lyric "I feel like me and Taylor might still have sex," but doesn't address her referring to as "that b---h" in the subsequent line.


"If people ask me about it, I think it would be great for me to be like 'he called me and told me the lines before it came out, jokes on you guys, we're fine,'" Swift says in the video.


The "Shake It Off" singer hasn't responded to Harris' online rant, but she did fire back at Kardashian after she shared the video.


"Where is the video of Kanye telling me he was going to call me 'that b---h' in his song?" she wrote on Instagram. "It doesn't exist because it never happened."


Swift has remained silent on the situation since, but Kardashian recently starred in a Snapchat video of her singing along to the lewd lyrics about Swift in "Famous" at a Vegas nightclub.
