Gwen Stefani and Blake Shelton have reportedly hired a wedding planner.

The 46-year-old singer confirmed her relationship with The Voice coach Blake last November (15) after finalizing her divorce from Gavin Rossdale the month before.

Rumors of a potential marriage have been circulating for months, and TMZ.com now report the pair have enlisted the services of famed wedding organiser Jerri Woolworth.

According to the website, Jerri has planned events for the Country Music Awards (CMAs), the National Football League (NFL) and the National Hockey League (NHL), ranging in size from 15 to 15,000 people.

Jerri has offices in Tennessee and New York, and her website states she is well versed in organising celebrity nuptials.

"Jerri Woolworth and her team of professionals have an understanding of, and abundant experience in celebrity wedding planning," the website states. "They have exceptional knowledge in organising multifaceted celebrity security not only for their celebrity clients but also for the multitude of its high-profile guests’ security... the privacy challenges from fans/public and confidentiality with vendors and service providers." Both Gwen and Blake have been married before - Gwen to Bush frontman Gavin and Blake to country singer Miranda Lambert.

TMZ contacted Jerri about the claims but were told she had "no comment". The website adds they are unsure whether a date has been set for the big day.

Gwen addressed rumors alleging she and Blake are secretly engaged on 94.7 Fresh FM’s The Tommy Show during an interview in June (16)."Let’s just take it one day at a time," she shrugged when asked about the claims. "Everything’s crazy right now so no, absolutely not."
