Blake Shelton, Gwen Stefani Together Even Before Divorce? [News & Rumors]

Gwen Stefani's estranged husband, Gavin Rossdale, apparently had doubts that the rock singer's relationship with her The Voice co-mentor started even while they were married with their respective partners. The timing of their divorce and Blake Shelton's divorce seemed to be perfectly timed and not coincidental at all.

TMZ reported that Rossdale is now under the impression that Stefani and Shelton had been cheating even before each other divorces were finalized. The two apparently were already involved as they attend to their responsibilities as mentors for The Voice, the report said.

Rossdale also believes that Stefani's song titled "Used to Love You" pertains to her own cheating and not his, TMZ said. According to the report, Stefani was only trying to cast the blame to her ex-husband, painting him as the bad guy and falsely accusing him of being a control freak. According to a source, Stefani prevented Rossdale from going on tour with his band because she was paranoid about her very own conduct.

Whatever the case maybe, Rossdale had been trying to move on. He was spotted looking calm in Beverly Hills on Friday, People reported. He was smiling as he carried tennis racquets. Interestingly, the 50-year-old British musician was still wearing a ring that appeared to be a wedding band.

The couple's split was never an easy one. After all, they have three sons together and their separation happened after sharing 20 years of memories together - seven years of being a couple and thirteen amazing years of being husband and wife.

In August, a source for People revealed that the estranged couple "were trying to make it work for the kids" even if they "have been living separate lives." For their children, "they are trying to keep things as normal as possible," the source said. "On the outside, their family life seems pretty normal. It doesn't seem like their separation has affected their day-to-day life. For Gwen and Gavin, their boys always came first," the source went on saying.

Not more than three months after, Stefani was already being linked with Shelton who had recently divorced from Lambert. The musician was said to have fallen hard, head over heels to the No Doubt singer.

A source who has spoken exclusively with the Hollywood Life said Shelton loves Stefani because she let him be. "He doesn't have to put up an act, he doesn't have to stop being immature and goofy when he needs to be with his friends and she lets him not have to deal with any pressure," the source revealed.

The word around town was that Shelton and Stefani had already spent a romantic getaway together in Nashville on Nov. 4 and were even snapped holding hands. The two seemed to be very comfortable with each other as they roam around dressed casually. "Blake feels completely normal around her, and it is a breath of fresh air," the source went on saying.
