“Jennifer and Calvin discussed a possible music collaboration during her birthday party,” a source tells PEOPLE.
Newly single Harris attended Lopez’s 47th birthday party in Las Vegas over the weekend, even taking in the singer’s hit Planet Hollywood concert All I Have.
“They discussed the types of music they both love. Calvin was excited to be at the party, hanging out with Jennifer and chatting with Benny [Medina],” the source added.
Though Lopez has never created music with the Scottish producer before, his musical resumé boasts several impressive (and lucrative) partnerships.
Harris has previously worked with ex Taylor Swift on his latest hit “This Is What You Came For” featuring vocals by Rihanna, who he worked with previously on “We Found Love.” In addition, Harris has also collaborated with Mary J. Blige, Kylie Minogue, Ellie Goulding, Rita Ora, John Newman, Florence Welch, Ne-Yo, Cheryl Cole and Gwen Stefani.
