"The Voice" judges Gwen Stefani and Blake Shelton's budding romance was recently confirmed, but Stefani's ex-husband, Gavin Rossdale was spotted still wearing his wedding band despite divorce settlement.

According to Entertainment Tonight, the 50-year-old Bush crooner was out and about for a coffee run in Studio City, California, when he was seen with his wedding band still on. It was only three months since he and the "No Doubt" singer called it quits after being married for 13 years.

The publication added that in the midst of the couple's fresh split, Rossdale has stepped out of the spotlight lately, while his former wife, Stefani, has been in the limelight lately after confirming her relationship with fellow judge, Shelton. The new relationship came just three months after Stefani and Rossdale's split. Shelton was in a completely similar situation, after he had broken up with his former wife, Miranda Lambert, just four months ago.

Even though Rossdale appears to be left behind by his former wife in terms of dating, the singer has not talked about Shelton and Stefani's new romantic venture.

However, one report by TMZ claimed that Rossdale was suspicious of the budding relationship's "timing."

While it was only days since Shelton and Stefani announced their relationship, a source told TMZ that Rossdale believes that the pair did not, in fact, got together just a few days ago, as he speculated that it was going on for quite some time now.

The source even said that Rossdale knew something fishy about the new pair even before they filed their divorce. Meanwhile, although he believes the timing of his divorce was "suspicious," it was reported that Rossdale thinks Shelton and Lambert's split is just something coincidental.

To cover up with Stefani's alleged cheating, the source close to Rossdale also revealed that "Gwen was painting him as a bad guy."

The report also revealed that Rossdale thinks Stefani and Shelton kept their relationship for quite some time because the "Hollaback Girl" singer was afraid that he will ask for more money if Rossdale knew she had cheated on him.

In 2002, Rossdale and Stefani wed in a Christian ceremony and had three kids -- 9-year-old Kingston, 7-year-old Zuma and 1-year-old Apollo. Currently, the estranged couple has joint custody over their children.
