Is there a special term for exes who stay friends? Some version of Friends Who Used To Have Benefits? American Idol alum Pia Toscano broke up with Dancing With the Stars pro Mark Ballas just over a year ago, but they are still fairly close (literally — Mark said she lives down the street from him.) They were both at the Camp Ronald McDonald for Good Times Halloween carnival on Sunday (October 21) in LA.

Mark is a musician as well as a pro dancer, and he and Pia both performed, though separately.  "I came out to play and hang," Mark told People. "I'm just going to finish [my latest] album over the winter and keep it moving. I've been playing a lot of shows."

Mark shared some photos of the event on Instagram, including shots with Pia and DWTS Season 14 alum Roshon Fegan. After the show, Mark tweeted, “sounding great as usual @PiaToscano.” He also shared her reply, “;) RT @PiaToscano @MarkBallas thank you ! U sound great as well :-).”

So mature! But Mark is single now, and since Pia lives just down the street, maybe someday they can try to give the romance another try. Just go over and ask to borrow a cup of sugar sometime!

Catch a new episode of Dancing With the Stars Season 15: All-Stars on Tuesday, October 23 at 8 p.m. on ABC.
