Fans respect Blake Shelton from The Voice for being the last original coach standing, but some viewers aren't supportive of the country singer's relationship with the glam pop star, Gwen Stefani. Blake and Gwen have been one of the most prominent power couples in the music industry since they started dating in 2015. However, there are skeptics who don't like the way that their relationship may have started. From the end of both stars' former marriages to fans' grappling with The Voice coach's marriage with Gwen today, here's why Blake's fans don't think his relationship with the "Hollaback Girl" singer is "Cool".

Fans first saw Blake and Gwen together in 2014 when Gwen was the newest coach on The Voice season 7. After meeting on the reality show, they swiftly embarked on a romantic journey. They announced that they were an official couple in 2015, and Blake and Gwen seemed to be inseparable. From going to awards ceremonies together to collaborating on new music, The Voice stars were everywhere, and they quickly had one of the most talked-about relationships in the pop culture realm. Nothing could get between the musicians, as even the COVID-19 pandemic strengthened their bond. Gwen said they spend a lot of quarantine time at Blake's Oklahoma residence. By July 2021, Gwen and Blake were celebrating their wedding, but certain people didn't approve of their nuptials.

One thing that explains why Blake and Gwen's relationship has garnered criticism is the fact that both of the reality stars were in marriages when they first met on The Voice set. Before his relationship with Gwen, Blake was married to fellow country singer, Miranda Lambert. The pair had been dating since 2005 and finally tied the knot in May 2011. The musical duo was a natural fit, and most country music fans celebrated their union. Similarly, Gwen had been married to British musician Gavin Rossdale since 2002. Blake and Gwen's decade-spanning relationships ended during their first season coaching together on The Voice, prompting some fans to question the stars' fidelity. Specifically, some critics of Blake and Gwen's marriage speculate that their relationship started as an affair.

Many of the musicians' fans thought it was strange that both Voice coaches' marriages ended concurrently. After only a few years of being Miranda's husband, Blake shared with his co-stars that he was getting a divorce in July 2015. Gwen announced her breakup from Gavin in August 2015. While it's possible that both pairs of music stars were experiencing irreparable marital problems at the same time, some find this to be too much of a coincidence.

Only a few months after the end of their previous marriages, Blake and Gwen were committed to their new romance. The stars claimed that they bonded over their shared heartbreak, but some The Voice viewers believe that the coaches had a relationship before their marriages simultaneously concluded. A source that spoke with E! News shared that Miranda "was not surprised to hear of the romance between Blake and Gwen. They were always pretty flirty."

To date, Blake and Gwen are romantic and sentimental with one another. They haven't demonstrated any signs that their love is fading, but fans wonder if the couple's relationship foundation is solid. Many detractors question the pair's flirty on-set relationship before the official end of Blake's relationship with Miranda. Regardless of who approves of their marriage, The Voice coaches are currently enjoying their life as newlyweds.
