The actress, who has played Becky McDonald's irresponsible half-sister for six months, announced the surprise news during an interview on Loose Women this afternoon.
Asked what 2011 will be like for Kylie, Lane replied: "Fab! I'm going to be really busy as of the end of January, so I'm just relishing this time off that I've got at the minute."
The star added that fans can expect "wedding bells" in the coming months before naming David as Kylie's new husband.
She continued: "To be honest with you, I've not even read the scripts yet, but I think it comes about in Tenerife, so I'm told - but that could change. So that is going to be a really good combination - I can't wait to see what the writers have got planned."
Meanwhile, show bosses confirmed that David will return from holiday newly-engaged within the next few months, leaving his family stunned when he announces the identity of his fiancée. The pair then start making plans for a spring wedding.
A Coronation Street spokesperson said today: "Kylie and David are trouble as individuals so the thought of the two of them getting together is a nightmare prospect for both their families.
"But it will certainly make for exciting viewing for Corrie fans - Kylie and David are fantastic characters and there is no end to the trouble they will cause for everyone."
As announced yesterday, Lane is in the running for the 'Best Newcomer' prize at this year's National Television Awards. Holby City's Olga Fedori, EastEnders star Ricky Norwood and Emmerdale actor Marc Silcock join her in the category.
