Blake Shelton and Gwen Stefani are more affectionate as each day goes by. The couple was recently spotted at a store where the 39-year-old country singer used to frequent when he was still married with ex, Miranda Lambert.

Shelton and Stefani were seen shopping at Atwoods Ranch and Home store in Madill, Oklahoma last Wednesday, Dec. 23.

One customer, who was present at that time, was quick enough to take a photo of the couple and upload it on Facebook; Atwoods Madill also posted the photo on Twitter.

It seems that Shelton and Stefani are taking their relationship really seriously ever since they made it public. E! Online reported that the couple is getting deeper on a personal level.

A source for the outlet revealed that they are "steaming up" and are now "on the same page of life." The source continued that Shelton has been supportive of Stefani's three kids and found to be patient around them.

On Dec. 21, E! Online also confirmed that the voice coaches were spotted attending the engagement party of singer, RaeLynn, who happens to be Lambert's friend as well.

However, the "Mama's Broken Heart" singer was nowhere to be found in RaeLynn's engagement party photos, and that's because she reportedly was infuriated at how her ex appears to be stealing their mutual friends.

"Miranda is upset that Blake is now showing off Gwen to all their old friends in Tennessee. He's the one in the new relationship, yet he's also the one keeping their old friends," an insider exclusively told Hollywood Life.

While Shelton's relationship with his new girlfriend may be all over the news, Lambert is also making the headlines but due to a different reason — one that outraged many animal rights activists.

Lambert posted a photo on Instagram flaunting the fur coat she got as a Christmas gift from her grandmother.

Fans slammed the country singer and her love for fur. According to ET Online, Lambert has not responded to any of the negative things thrown at her.
