Los Angeles - Kim Kardashian West chatted to Calvin Harris at Jennifer Lopez's birthday party on Friday.
The Keeping Up With the Kardashians star - who last week leaked footage of the DJ's ex-girlfriend Taylor Swift talking to Kanye West about his controversial track Famous - was seen locked in conversation with the Summer hitmaker at the Las Vegas bash, though it is unclear what they were discussing.
A source told Us Weekly magazine: "Kim and Calvin did talk and interact, smiling and chatting for awhile."
Kim - who presented the birthday girl with a cake at the bash, which took place after Jennifer's All I Have show at Caesar's Palace - reignited her and husband Kanye's feud with Taylor last week when she leaked the footage, prompting the Bad Blood singer to hit back and insists she had never given the rapper "permission" to reference her in the track as she had no idea he referred to her as a "bitch".
Other guests at Friday's party included French Montana, Cristiano Ronaldo, Maria Menounos, John Stamos, Iggy Azalea and LA Reid.
Jennifer - who turned 47 on Sunday - ended the evening by joining singer Tank at the piano to perform songs including 'End of the Road' and 'My Girl'.
Meanwhile, the 32-year-old DJ appeared to take the side of Kim and Kanye over his former girlfriend again when he shared a video of himself signing along to Kanye and Schoolboy Q's song That Part.
