While female Yankee fans are buzzing about Derek Jeter's new single status, sources on the set of Charlie's Angels
in Miami are talking about a growing late-night friendship between his ex Minka Kelly and her costar Ramon Rodriguez.
"We have seen Minka and Ramon talking in his trailer way after hours, and often late into the night," a source on the set tells PEOPLE. "They have been together long after they need to be for the show."
Another source isn't so quick to couple them up: "They're just friends. Ramon is basically the only guy on set so of course they all hang out with him."
Kelly, 31, had been dating Jeter, 37, for the past three years with annual talk about an impending lavish wedding.
It wasn't meant to be however, with the couple announcing their split Thursday
, and a source telling PEOPLE they still "care about each other and … are still friends."
Puerto Rican-born Rodriguez, also 31, who is best known for his TV roles in The Wire
and Day Break
, plays John Bosley on ABC's Charlie's Angels
reboot – a much younger version than fans are used to.
A rep for Rodriguez didn't immediately comment. An ABC rep declined to comment.
