They were reportedly on good terms and happy for one another's new relationships, but a new report suggests that Miranda Lambert is still pretty mad at Blake Shelton--and has a huge revenge plan in the works to stick it to her ex.  

Miranda Lambert Flaunts New Romance On Instagram

According to reports, Lambert is still peeved about the fact that her ex-husband moved on so quickly after their divorce with Gwen Stefani, and has decided that her own new romance with Anderson East will give her the perfect vehicle for revenge: a baby.  

"[She's] on a quest to have a baby," sources reportedly said. "Payback's a b***h. Miranda is fired up." 

Did Blake Shelton Give Gwen Stefani The 'Best Present Ever?'

Though a reason for Shelton and Lambert's marriage ending has never been officially stated (the couple didn't announce their split until the day it became official in July), rumors have swirled for a while that they had major disagreements over having kids, with Shelton eager to become a dad, while Lambert was hesitant to become a mom.  

Now, with the new rumors, it appears Lambert sees having a baby with East is a great way to stick it to Shelton, whom she wouldn't have a baby with in their ten years together, four of which were spent married. East has only been Lambert's boyfriend for around two months.  

The reports also come after several that indicated Shelton and Stefani were also expecting a child together, though the couple has vehemently denied all of those rumors.
