Blake and Gwen started dating in late 2015, shortly after their respective marriages to Miranda Lambert and Rossdale fell apart. Sources tell Us Weekly the couple is keen to wed but Stefani is still fighting to get her marriage to Gavin annulled by Catholic church officials, stating, "Gwen's religion has always been extremely important to her, and Blake is completely supportive of this."
Stefani and Rossdale wed in 2002. They reached a divorce settlement in August, 2016.
Meanwhile, Shelton also ended his marriage to Lambert in 2015 and quickly divorced the singer, who has remarried New York police officer Brendan McLoughlin.
