The unlikely duo, who have both been publicly at odds with Taylor Swift — for very different reasons — were brought together at an early celebration of Lopez’s birthday, after her “All I Have” show at Caesar’s Palace, which Kardashian, 35, attended.
“Kim and Calvin did talk and interact, smiling and chatting for awhile,” the source confirms to Us, though it's unclear what the pair discussed.
Other guests at the star-studded bash include soccer star Cristiano Ronaldo, Iggy Azalea, Maria Menounos, LA Reid, John Stamos and French Montana. The crowd sang happy birthday to Lopez as she entered the room, with Kardashian presenting her with a large cake, before J. Lo kissed her boyfriend, Casper Smart.
According to the insider, Lopez excitedly ended the night by jumping on the piano to sing songs such as “End of the Road” and “My Girl” with the singer Tank.
Kardashian and her husband, Kanye West, reignited their feud with Swift, 26, on Sunday, July 17, when the reality star shared a video clip of the rapper and the “Wildest Dreams” singer chatting about the lyrics for his hit “Famous” over the phone.
Swift fired back at Kardashian and West via Instagram on Monday, July 18, claiming that West, 39, never asked for permission to call her “that bitch” in his controversial song. (Kardashian Snapchatted a clip of herself singing along to “Famous” in Vegas on Saturday.)
Harris, meanwhile, launched into a Twitter rant against his ex-girlfriend on Wednesday, July 13, after it became known that Swift had a hand in writing his summer hit “This Is What You Came For,” slamming her and her team for going “out of their way to try and make ME look bad at this stage.”
“I figure if you’re happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do,” he tweeted in reference to Swift’s whirlwind romance with Tom Hiddleston. “I know you’re off tour and you need someone new to try and bury like Katy [Perry] ETC but I’m not that guy, sorry. I won’t allow it. Please focus on the positive aspects of YOUR life because you’ve earned a great one. God bless everyone have a beautiful day.”
