Gwen Stefani's husband, Gavin Rossdale, is reportedly moving on from their marriage even though their divorce is yet to be finalized.

According to a report, Rossdale was reportedly spotted kissing another woman in a recent event.

"Gavin brought a beautiful tall brunette woman to the event and, at first, it seemed that it was his publicist or something. They came in together and sat next to each other at dinner, but made sure to keep their distance because they knew people were watching them," a source reportedly told Radar Online, as quoted by Celeb Dirty Laundry.

"After drinks started flowing following dinner, Gavin followed her to the bathroom at the same time I was walking towards the restroom. She left the restroom just before I did and when I walked out, Gavin and her were kissing!" the insider dished out.

It seems that Gwen Stefani's husband is not looking back on his marriage and is already playing the field.

However, there are speculations that Rossdale could have exerted more effort on dating after Gwen Stefani was rumored to be getting close to her "The Voice" co-mentor, Blake Lively, who is also recently divorced himself.

According to previous reports, Gwen Stefani and Blake Shelton have purportedly been inseparable ever since her divorce with her husband and his split with his wife.

"The Voice" insiders have reportedly noticed that the two spent more and more time in each other's dressing rooms.

"When they're not together, Blake has been calling her, too," an insider reportedly told Life & Style, as quoted by CDL in a previous report. "He's even given her some small gifts."

Could the No Doubt singer's husband be using his date to show his ex that he could move on from their split faster than she can?

Gwen Stefani and her husband have three kids together.
