Blake Shelton Embarrasses Girlfriend Gwen Stefani When He Talks About Their Flirting

Blake Shelton is very much in love with his girlfriend, Gwen Stefani.

On Friday, Shelton had a concert in Oklahoma and at one point, his girlfriend joined him on stage. Shelton planted a kiss on Stefani and embarrassed her when he spoke up about the early days of their romance.

"We were starting to hang out together and mess around," Shelton, 41, told the audience who gave a warm response by cheering on him, Entertainment Tonight reported. Meanwhile, Stefani rested her head on his shoulder and gave her a mock-surprise look. "You know, texting each other, starting out as friends."

Shelton's concert was held for around 150 fans in Tishomingo to promote his first restaurant, Ole Red. The event also aims to raise money for the local charity Johnston County Reaching Out.

Shelton and Stefani have been dating for almost two years. Based on their relationship timeline, the pair met on the set of "The Voice" when Stefani was hired after Christina Aguilera took a leave of absence to welcome her upcoming daughter.

Both were previously married and are divorced. When Stefani joined the reality singing competition in 2014 she tagged her then-husband Gavin Rossdale along to be her team's mentor. As they film for the show, Stefani and Shelton became closer along with Adam Levine and Pharrell Williams.

On July 20, 2015, Shelton and Miranda Lambert announced their divorce. On Aug. 3, 2015, Stefani and Rossdale announced their split. Since both are going through the same tough time, they became even closer.

In November 2015, Stefani was asked about Shelton and she joked about their rumored fling. "I think that NBC did that. Two divorced people at the same time," she told Entertainment Tonight. "I'm not going to answer that right now, Ryan. I think I've given enough of myself this morning to you. But I think he's hot, don't you?"

Things became official shortly after Stefani's interview with Ryan Seacrest. "Gwen and Blake are longtime friends who have very recently started dating," Shelton's rep told Us Weekly to confirm their romance.
