Blake Shelton-Gwen Stefani Update: Is Miranda Lambert’s Ex Cheating On Stefani Amid Engagement, Wedding Rumors?

Blake Shelton has not given up "flirting" with other women despite dating Gwen Stefani, according to a new report by OK! magazine. However, Gossip Cop debunked the report saying that Shelton is not "betraying" his new girlfriend whom he started dating after his divorce from Miranda Lambert.

According to OK! magazine, Shelton recently "knocked back a few drinks at this bar and then started blatantly coming on to the bartender," the source said, adding: "To Blake, being in a relationship doesn't mean you have to stop flirting ... if she does find out, he'll try to play it off."

The OK! magazine report, cited by Gossip Cop, also said that Stefani would be heartbroken if she found out about Shelton's flirtatious behavior. Stefani "sees Blake as her knight in shining armor," the source reportedly said, adding that she feels her "Voice" co-star "saved her when she was at her lowest and made her believe in love again."

Stefani, who was married to Gavin Rossdale for 13 years, announced her divorce in June, following which she was seen getting close to Shelton on the sets of "The Voice."

Reports surfaced over the weekend that Stefani and Shelton are planning to get engaged. The National Enquirer reported that things are moving quite fast for the new couple as the 39-year-old "Sangria" singer brought Stefani, 46, to his Oklahoma home to meet his family. According to a source, Shelton wanted the approval of his mother, Dorothy, and stepfather, Mike Shackleford, before proposing to Stefani. The source reportedly added that Shelton was hoping to marry Stefani next spring.

However, Gossip Cop reached out to Stefani's representative who told the site that the National Enquirer’s story is "untrue."

Shelton and Stefani were reportedly photographed last week showing off some serious PDA during a date night at Casa Vega Mexican restaurant in Studio City, California. The two were seen hugging and kissing outside the restaurant while waiting for their car.
