Miranda Lambert, 33, is about to get honest about her complicated breakup from Blake Shelton. The former's sixth studio album, dubbed "The Weight of These Wings," is all about her breakup with "The Voice" coach and her current relationship with Anderson East.

With Maranda's album making the headlines, it has been speculated that Shelton is not happy with his girlfriend Gwen Stefani listening to his ex's new album. The latter is reportedly obsessing over Lambert's music, but has not listened to it yet because Shelton does not want her to listen to what his ex-wife has to say about their breakup.

"But she hasn't listened to it yet because Blake [Shelton] is currently living at her house in Beverly Hills while he's taping 'The Voice' in LA," a source told In Touch magazine, as cited by Aussie Network News. "He has a rule that Miranda [Lambert]'s music isn't played - ever."

It comes after Shelton and Stefani reportedly finalized their wedding plans. The two are reportedly planning to make it official on May 5, 2017 at the Beverly Hills' Church of the Good Shepherd.

"They can hardly agree on anything," a source told Celebrity Insider. "Gwen wants to go big on this - and Blake wanted to make it an informal affair down home in Tennessee or their new place in Oklahoma - but he's not willing to go to the mat against her."

The source went ahead to reveal that Stefani's guest list is around 400 individuals alone, which includes Jennifer Aniston, Justin Theroux, Katy Perry, Courteney Cox and Johnny McDaid. The two are also considering inviting Stefani's ex-husband, Gavin Rossdale, and Shelton's former wife.

The couple has reportedly picked Jon Bon Jovi's "Blaze of Glory" as their wedding song and has decided to perform it at the banquet themselves. Since Stefani wanted an extravagant wedding, she agreed to pay all the expenses, while Shelton will shoulder their honeymoon, the source added.

Stefani and Shelton, who have a combined fortune of $225 million, has reportedly signed a prenuptial agreement. The latter's Oklahoma farm will remain under his name, while the mother-of-three will keep her Beverly Hills' chateau under her. Neither will seek spousal support should the marriage ends.
