It was reported earlier this year that Rita could be set to leave the show having only joined this year.
It'd make Rita the third new female coach in three years with Jessie J and Kylie Minogue having also both decided not to stick around.
Asked about coming back next year, Rita said this week: "Ooooh. That’s THE question... Let me get through this series first."
Speaking to the Daily Mirror newspaper, a source said: “She has a constantly busy diary with things in the UK, the US and Asia – she just keeps landing amazing gigs.
"There’s no way of knowing what her diary will be like next year yet.”
Even if Rita isn't back next series - which will actually be filmed later this year - Rita revealed that being on the show has already brought some benefits, apparently thanks to all of its OAP viewers.
“I go to Tescos to pick up flowers for my mum every week, when I’m in town. I see grandmothers and they say ‘You’re doing really good on The Voice.’" Rita said. "And I’m like ‘You know who I am!’ So thanks to The Voice for expanding my fanbase.”
For now, The Voice UK live shows kick off this Saturday at 7:15PM on BBC One.
