Earlier this week it was revealed that Lambert was dating Felker, the frontman of Turnpike Troubadours. The couple reportedly got together on her Livin’ Like Hippies Tour that began in January.

The relationship allegedly “just happened” when the two singers “started spending a lot more time together while on the road,” an insider told Us Weekly.

Following the reports that Lambert and Felker were dating, the “House That Built Me” singer’s ex-husband Blake Shelton, 41, tweeted about “karma” but did not specify what he meant.
