HEATHER & JACK IN MARRIAGE SHOWDOWN

Heather Locklear and Jack Wagner

Soap star JACK WAGNER and wife-to-be HEATHER LOCKLEAR are in a bitter showdown over doing reality TV — and she’s angrily threatening to call off the wedding.

“Jack is a big fan of reality TV and has noticed how celebrities have been cashing in by letting camera crews into their homes,” a friend of Heather’s told The ENQUIRER.

“He’s excited to jump on the reality bandwagon and asked Heather to star in a show following their joys and troubles in the run-up to their big day next summer.”

Jack, 51, believes that a reality show, which would also feature his two sons and Ava — Heather’s daughter with rocker RICHIE SAMBORA — has the makings of a ratings winner.

But Heather, 49, feels she is above reality TV and despises the idea of a film crew intruding into her daily life, disclosed the friend.

“She considers herself a serious actress, and the thought of letting lights and cameras into her home in the morning before she puts on her makeup really fills her with dread. Heather told Jack that she’ll pull the plug on their wedding if he persists with the idea.”

Another source noted that Heather’s life is back on track after her struggles with substance abuse “and she doesn’t need a reality TV show creating more drama than necessary.

“She prefers to spend her time acting, being a mother and playing golf with Jack rather than putting her entire life on display.”
