AceShowbiz - Even though Blake Shelton and Gwen Stefani have been dating for a few years, they have never revealed any intention to take their relationship to a new level. However, it has been reported that the couple is actually more than ready to get married, but they need to clear an obstacle first before exchanging their vows.

According to Us Weekly, the reason why the singers put their wedding plan on hold has something to do with Gwen's Catholic background. A source tells the publication that the No Doubt singer "began the formal process" to have her marriage to Gavin Rossdale annulled by Catholic church officials "so she can marry Blake and have it be recognized by the church."

The insider continues saying, "Gwen's religion has always been extremely important to her. Blake is completely supportive of this."

According to AOL, Catholicism states that if a previous marriage is not annulled, a person is not allowed to receive communion. In 2015, Pope Francis took steps to make the annulment process easier, quicker and less expensive. Thus, should the report be true, it seems fans will only have to wait a little bit longer until Gwen and Blake make official announcement.

Blake and Gwen started dating in 2015 after meeting on the set of "The Voice". The couple has always been hit with engagement and marriage rumors ever since their romance began, but the two continued to debunk them all. In late last year, the "Hollaback Girl" singer said that the pair would take their time before they walk down the aisle.

"There is zero pressure," she said on "Today". "I think when there's trauma, the way we had trauma back in the day, going through all these hard times, to get to a place where you find somebody that's like your best friend that you know that you can depend on and trust and just go through life. I think that we're just trying to be in the moment as much as we can."
