The 34-year-old singer recently got engaged to Andrew Levitas, reported Daily Mirror.
When asked if she would be singing at the ceremony, Jenkins said, "Can I have a day off for that? I've got some friends I can ask."
Speaking about her engagement, Jenkins added that she's "very, very happy and I'm starting to think about wedding plans and all of that."
"I'm very lucky to have met such a lovely man, he's from New York and proposed to me in the Hamptons... He went down on both knees - I think he got it wrong."
