Blake, Gwen wedding ‘plans’

AMID speculation this week that Blake Shelton and Gwen Stefani could soon be engaged, the pair’s already reportedly hired a celebrity wedding planner, Jerri Woolworth.

Woolworth — who’s based in Tennessee and has planned mega-events for the NFL and CMA Awards for up to 15,000 people — has been hired for the wedding of “The Voice” co-stars, who began dating last year after each going through a high-profile breakup, TMZ reported Friday.

Earlier this week, reports said an engagement could be imminent: A source told People that although Shelton has not yet popped the question, “everyone is expecting it to happen at some point.”

But apparently things are moving more quickly! When Page Six reached wedding planner Woolworth on Friday, she had no idea that a story about her part in Shelton and Stefani’s alleged nuptials had leaked. A nervous-sounding Woolworth told us she couldn’t confirm any details.

Then again, it’s not uncommon for celebrity wedding and events planners to sign nondisclosure agreements. Vendors had to sign confidentiality agreements for the 2014 wedding of Dwyane Wade and Gabrielle Union, and Kim Kardashian and Kanye West also reportedly required the agreements and even banned cellphones from their blessed event. Beyond wed- dings, workers at a Justin Bieber “Gatsby” party in 2013 reportedly had to sign a contract that would leave them on the hook for $3 million if they violated it by spilling the beans.

Woolworth has said that her events provide “multifaceted celebrity security” for celebs and their VIP guests, and also that “Woolworth thinks big . . . no, HUGE.” So don’t expect subtle!

Shelton and fellow country star Miranda Lambert announced in July 2015 that they’d divorced. Stefani and ex-hubby rocker Gavin Rossdale separately said a month later they were divorcing after nearly 13 years — amid rumors of Rossdale’s infidelity with a family nanny.

A rep for Stefani had no comment.
