Are Keiko and Marc from Globe a couple?

Looked up globe for the first time in ages – Keiko had a hemorrhage back in 2011 and hasn't performed since. She'd been married to her globe bandmate TK for years, but they divorced after he was caught having an affair with Keiko's live-in nurse.

Didn't really see anything new, but I looked at Keiko's X – her feed is pretty much exclusively selfies with her other globe bandmate, Marc.

Are they a couple now???
