Gwen Stefani and Blake Shelton’s romance may come as a shock to everyone at first, but the former No Doubt frontwoman and the 40-year-old country music singer, songwriter, and television personality proved to everyone that their relationship is the real deal.

In fact, “The Voice” judges have so much love and respect for each other that the L.A.M.B. fashion line founder is not even threatened if her beau will run into his ex-wife, Miranda Lambert.

“Gwen [Stefani] couldn’t care less if Blake [Shelton] runs into Miranda [Lambert] at the CMT Awards or anywhere else,” an insider told HollywoodLife.

“She’s never been so completely secure in a relationship before. Blake makes her feel like a queen so that gorgeous women could surround him, and she wouldn’t mind.”

Gwen and Blake's romance gets stronger and stronger by the minute

Gwen Stefani and Blake Shelton’s relationship has been going strong since 2015 when they worked together as judges on the NBC American reality talent show, “The Voice.” The duo was experiencing a similar path with their personal lives at the time that they quickly bonded over it.

Gwen Stefani ended her 14-year-marriage to Gavin Rossdale, after his infamous cheating scandal with the nanny. The 47-year-old singer, songwriter, fashion designer, actress, and television personality share three children, 11-year-old Kingston, 8-year-old Zuma, and 3-year-old Apollo with the lead singer and rhythm guitarist of the rock band Bush.

Blake Shelton, on the other hand, and Miranda Lambert called it quits after four years of marriage. The country superstar has previously revealed that he and his ex-wife have decided to skip the drama. The duo finalized everything just hours after their announcement, so it went smoothly and quickly.

"In Oklahoma, it happens so fast," Blake Shelton told the Bobby Bones Show at that time, as per Entertainment Tonight.
