Gwen Stefani 'leaks' Blake Shelton's new album tracklisting

Country star Blake Shelton has recruited his girlfriend Gwen Stefani to playfully 'leak' the tracklisting for his new album.

The Honey Bee singer debuted the cover art for If I'm Honest on Monday night's (18Apr16) episode of talent show The Voice, on which he serves as a mentor, and on Tuesday (19Apr16), Gwen took to social media to reveal the project's 15 song titles.

"Look what I found lying 'round the house!" the blonde beauty exclaimed as she shared a photo of the back of his new CD.

She then added the hashtags "#ispymyname" and "#goaheadandbreakmyheart", highlighting the name of a duet between the two lovebirds.

The news emerges five months after the stars were rumoured to have taken their chemistry into the studio to work on a country tune together. At the time of the reports in November (15), shortly after the couple made its romance public, a source told People.com, "It's amazing how good she sounds on a pretty country song. And it sure is good to hear Blake singing real country again."

The insider claimed the track was about a broken relationship, but fans will have to wait until 20 May (16) to hear the new material.

If I'm Honest also includes Blake's new tune for The Angry Birds Movie, titled Friends, and a collaboration with the Oak Ridge Boys, called Doing It to Country Songs.

The 39-year-old recently revealed another track on the album, his latest single Came Here to Forget, was inspired by events in his personal life, following his July (15) divorce from fellow country singer Miranda Lambert and his subsequent romance with Gwen.

"I've had a lot of music over the years, but I don't think I've ever had a song before that's such a direct look into my life," he admitted.

Meanwhile, Gwen has also been channelling her feelings for Blake into her new music, after confessing her single Make Me Like You, which features on her new album This Is What The Truth Feels Like, was written about their blossoming romance.

The stars became a couple in October (15), two months after Gwen revealed she was divorcing her husband, Bush rocker Gavin Rossdale.
