The Voice stars have had their relationship on full display since going public with their romance at the end of October. Now, after almost six months together, Shelton is looking to get engaged, Us Weeklyreported.
"Blake could propose to Gwen very soon... He hasn't been this happy in years!" a source close to the country singer told Us. "Gwen is everything he wants."
For starters, Shelton has always wanted children, and Stefani is a package deal with her three sons -- Kingston, 9, Zuma, 7, and Apollo, 2 -- whom she had with ex-husband Gavin Rossdale.
When to start a family was reportedly a point of contention in his marriage to Miranda Lambert and part of the reason why they split in July of last year.
"With Gwen, Blake has the family life he'd hoped to have with Miranda," the source said. "[And] her kids love him as much as she does."
Stefani is also "willing to try" to get pregnant again with Shelton, because according to the source, he still "wants kids of his own."
However, a new baby might be tough for the couple considering their careers have peaked, and with that comes very busy and hectic schedules.
Shelton will be releasing his twelfth album If I'm Honest on May 20, while Stefani is promoting her new record This Is What the Truth Feels Like.
"Gwen texts Blake a million times a day," an insider told the magazine of the couple's great communication. "But he doesn't mind at all."
Shelton has served as a mainstay coach on The Voice since Season 1. The show is currently airing its tenth edition, during which Stefani had advised her boyfriend's team for the infamous "Battle Round."
