Gwen Stefani and Blake Shelton are ready to head down the aisle.

The 51-year-old No Doubt singer and the 44-year-old country star announced they got engaged back in October after five years of dating.

The couple, along with Stefani's three sons – Kingston, 14, Zuma, 12, and Apollo, 6 – are spending most of their time during the pandemic at Shelton's Oklahoma ranch and it holds a very special place in their hearts.

So much so, Shelton and Stefani want to marry there. “Blake built a chapel on the grounds of his Oklahoma ranch. He did it himself with help,” a source told Us Weekly.

“It’s really a tribute to their love. They are going to get married in the chapel, most likely early next year," the insider added.

Before he proposed, Shelton reportedly asked permission from her three sons. A source told People magazine, “Blake told her boys that he wanted to propose and ask their permission."

“Her family very much approves of him. He’s an amazing partner and a great dad to the boys. Gwen is ecstatic. The proposal was a surprise," the source claimed. 

For her birthday in October, Shelton gushed over his love. "It’s a special day for a special lady in my life," he wrote. "I’d write a song for you every single day if I could..."
