Blake Shelton is keeping several secrets from Gwen Stefani, including that about his “serial cheating” and “constant boozing,” the National Enquirer claimed. The news comes just days after the same tabloid reported that Shelton recently got close to a mystery woman by draping his arm around her to make his girlfriend jealous.

According the new report, Shelton had cheated on his ex-wife Miranda Lambert with at least eight other women during the time they were married. The report also claimed that "The Voice" coach tried to get close to stars like Scarlett Johansson, Christina Aguilera, and Shakira, among others. However, Gossip Cop debunked the report stating that Shelton made no such move.

The rumors about Shelton cheating on Stefani comes as Life & Style magazine reported that the latter proposed her boyfriend for marriage.

According to Life & Style magazine, Stefani “surprised her boyfriend with a lavish private dinner and a marriage proposal," just days before Shelton hosted the Kids Choice Awards earlier this month, Gossip Cop reported.

“The pop star asked her beau of less than a year to marry her,” a source told the magazine. “He was in shock,” but still managed to say, “Yes.”

However, Gossip Cop reported that the news was false.

Stefani and Shelton made their relationship public in November, and since then have been surrounded with several rumors, including recent reports of pregnancy and miscarriage.
