While Blake Shelton hasn't been shy about showing off his relationship with Gwen Stefani, his ex wife Miranda Lambert has been keeping her love life more on the down-low since their divorce. But the country singer made it clear who her new man was on Friday night, by wearing his name on her t-shirt during a concert in California.

Lambert took to the stage in a pair of cut-off jean shorts and fishnet stockings while wearing the tee which read ‘Anderson East’. The couple have never publicly spoken about their relationship, but they have shared a few romantic posts on Instagram, beginning in January.

Last month Lambert released single ‘Vice’, her first new material since 2014’s Platinum. Opening up to Billboard earlier this month about getting back to writing after her divorce, Lambert said: “I’m nervous as hell.”

“I’m pretty straightforward in my music. I always have been, and that hasn’t changed. With my songwriting, it’s taking a journey with what’s been going on in my everyday life -- good, bad, ugly and everything in between. I feel like the right thing to do was just come out with something really honest.”

“Every record I’ve ever made has been a reflection of where I am right then in my life, however old I am. And I’ve never held back at all,” she added. “But this time with what I happened to be going through in my life, being honest was never really a choice. Everybody knew anyway. So I just said, I’m gonna journal it, and -- good days and bad days -- use it for my art.”
