ANN CURRY is finally free from her contract with NBC – and now it’s Matt Lauer’s turn to sweat!

Ann is being wooed to write a tell-all book on her years with the “Today” show, including dishing dirt on her colleague-turned-nemesis Matt, sources told The National ENQUIRER.

Ann’s $12 million annual deal expired in December, two-and-a-half years after her 2012 firing as Matt’s co-anchor. After that, she limped along as an NBC special correspondent, rarely appearing on camera.

Publishers hope Ann is ready to settle scores, sources said. “Ann had an amazing history on ‘Today.’ She was the news anchor for 14 years before being elevated to co-host, so she’s seen it all and knows all the skeletons in everybody’s closet,” a source divulged.

“Ann has all the dirt on Matt, Katie Couric, Al Roker and former co-host Meredith Vieira. She knows all about behind-the-scenes fights and tantrums, and she can command a multi-million dollar book deal to dish it all.”

Matt, 57, is quaking in his boots, insiders said. He was reportedly instrumental in Ann, 58, getting sacked after just a year as his co-host.

“Ann has had a ringside seat to what viewers don’t know about Matt – particularly the rumors he carried on affairs with ‘Today’ gals Natalie Morales and Savannah Guthrie,” the source added. “She can really sting Matt if she writes all that she knows!”

But Ann may hesitate to sign a book deal due to her association with NBC, and the fact she still might need the network, a friend added.

“Ann is savvy enough to know you don’t burn bridges,” said the source. “But after what she’s been through she may not care. Matt better hope she doesn’t go that route!”
