Blake Shelton and Gwen Stefani are making a comeback as judges in the upcoming new season of The Voice. In the first look for Season 19, Shelton, Stefani, and fellow returning judges John Legend and Kelly Clarkson shared what they have been up to during quarantine. 

The "Nobody But You" singers have been spending time together at Blake's ranch in Oklahoma, along with Gwen's sons, since the coronavirus pandemic started in March. But, their months away from their usual daily routine in California did not go unproductive. Shelton revealed that, while in lockdown, he learned how to make jam, specifically peach jam. 

The country singer said he has about six to eight peach trees at his ranch and every year, they harvest a bunch of peaches. Since they were held at the ranch this year and couldn't eat all of their harvests, they decided to make peach jam on their own. 

Blake Shelton said their hard labor yielded several cases of peach jam while showing off a photo of his creations. Blake added he probably won't do it again but at least he learned how to make a jam. 

As for Gwen Stefani, she learned how to make sourdough. The "Hollaback Girl" singer, however, admitted that it took her a month before she was able to get her starter right. Aside from sourdough, Stefani said she also learned gardening. 

It is also worthy to note that the couple also released "Happy Anywhere" while in quarantine. It was their fourth collaboration song. 

Meanwhile, John Legend and Kelly Clarkson also spent quarantine with their family. Legend admitted that he did not have a chance to learn a new hobby because he barely has free time even when they only stay at home. 

He explained that, aside from raising two toddlers with his wife Chrissy Teigen, he also spent the lockdown finishing up his new album, Bigger Love. The album was released in June.

Clarkson, on the other hand, continued working even while COVID-19 is ravaging the country. She's doing The Kelly Clarkson Show while on quarantine. 

The "Because of You" singer recorded several episodes of her show from her home in Montana and then, later on, at her Southern California home. Kelly returned to studio-shot with a virtual audience when the second season of the Daytime Emmy-winning show premiered this month. 

The Voice Season 19 is set to premiere on October 19 at 8 p.m. ET/PT on NBC. The singing competition was originally scheduled to kick off earlier this month but it was delayed for more than a month since the show wasn't ready to start with a new set up.
