Reps for both confirmed yesterday that the two "Voice" coaches have started dating. Gwen's rep issued the following statement ... "Gwen and Blake are longtime friends who have very recently started dating." This is obviously code for "Neither of them cheated on their now-estranged spouses."
Even if they hadn't admitted it, it would have likely blown up this morning anyway, because Gwen went to Nashville with Blake for the "CMA's". Although she wasn't at the ceremony, she did hit up the after-parties with him.
Meanwhile ... No one was blown away to hear Blake and Gwen are doing it, and that includes Blake's ex, MIRANDA LAMBERT.
"She was not surprised to hear of the romance," a source tells E! Online. "They were always pretty flirty. Miranda and Blake were on the rocks on and off and knew that this could always be a possibility."
Not only was she not surprised, she doesn't care. Adds the source, "She has nothing against Gwen. Whomever Blake is with she wishes them the best."
