"They've been able to support and relate to each other," says a source close to the couple
“There’s no pressure,” a source close to the couple – who attended The Voice‘s season nine after-party together following Jordan Smith’s win – tells PEOPLE.
Adds the source: “They’ve been able to support and relate to each other and have gotten through a very difficult and now triumphant time in their lives.”
Indeed, the No Doubt rocker, 46, and country star, 39, began dating this fall after each weathered very public splits. Shelton announced his divorce from Miranda Lambert in July, while Stefani and ex Gavin Rossdale announced their breakup just two weeks later.
Having bonded as costars on the NBC singing competition, the pair have helped each other through their heartache.
“Blake and Gwen are going through similar situations. They have … drawn support from each other,” a Shelton insider told PEOPLE early on in their relationship.
