Blake Shelton posted a tweet on Wednesday morning (4/25) that many are interpreting as a dig at his ex-wife, Miranda Lambert. Shelton tweeted, "Been taking the high road for a long time...I almost gave up. But I can finally see something on the horizon up there!! Wait!! Could it be?! Yep!! It's karma!!" While Blake doesn't specify who the tweet is about, a lot of people think it's in response to new rumors that Lambert is dating Turnpike Troubadours lead singer Evan Felker, who reportedly filed for divorce from his wife in February. Turnpike Troubadours performed a few shows on Lambert's "Livin' Like Hippies Tour" in February, shortly before gossip surfaced that Miranda and her boyfriend of two years, Anderson East, had split.
