Leah, 54, was diagnosed with terminal lung cancer in September 2016 but was told in March last year that experimental treatments for stage 4 lung cancer had stopped working.
The former Emmerdale actress decided to secretly marry her partner Jez Hughes, 44, in an intimate ceremony in Horsham, Sussex, before it is too late.
The ceremony took place in the drawing room at Park House, a grade II listed Georgian building, the Sunday Mirror newspaper has revealed.
And despite her heartbreaking diagnosis, the former Emmerdale star wakes up “excited” every day because she’s so relieved to still be alive.
“I wake up every day excited. I didn’t do that before the cancer.
“I’m just really glad to be here. I wasn’t expected to live that long, so I am just going to carry on, gloriously living, no matter what the doctors are saying.

“I could have died but I was still alive – that was a gift. I had time to tell my family how much I love them and decide how I wanted to live,” she said.
Last February, Leah said she planned to look on the bright side rather than dwell on the “negative stuff”.
“I’m going to choose to embrace life and going to choose to make positive decisions. I haven’t got the energy to react to negative stuff.”
The actress has grown-up daughters, Lily and Maya, and said telling them was the hardest thing about having cancer.
“Any mother will know how I felt. It’s the worst thing you can imagine having to tell those closest to you, something like this … trying to find the words. It’s the worst thing I’ve had to do.
“I think it’s almost worse for those close to you because they’re trying to look after and protect the person who’s poorly, not just physically, but emotionally,” she said.
Meanwhile, Leah, who played Zoe Tate in Emmerdale, has been tipped to return to the soap amid her nephew Joe Tate’s return and revenge plan.
She previously said she hasn’t been offered work since her diagnosis, and fans think the storyline is the perfect time for her character to return.
