Blake Shelton couldn't be more pleased with his latest album, If I'm Honest, becoming the No. 1 country music seller, and he's not alone.

After tweeting a music chart showing his name at the top, Blake's girlfriend, Gwen Stefani, replied with a tweet of her own.

"Crazy," the "Misery" singer wrote, adding the folded hands and applause emoji.

The announcement was made even more special by the fact that the album features a duet by the couple called "Go Ahead and Break My Heart"

In a recent interview with Rolling Stone, the 39-year-old country star opened up about how his relationship with Stefani influenced the album.

"I was spending some time with Gwen all of a sudden, and she became my closest ally, my friend, my person in my life who had my back, and I had hers," Shelton said. "[I] created this bond with somebody that I never would have thought in a million years."

The couple continues to have each other's backs, as Tuesday marked the release of Stefani's "Misery" video.

Shelton tweeted a promo for the video, writing, "It's here!"

With 153,000 copies of the album sold, If I'm Honest actually sold more physical albums than any other release this week -- country or otherwise -- but it lost the No. 1 spot to Drake's Views because of the rapper's overwhelming number of online streams.
