Miranda Lambert, Blake Shelton – We're Still Splitting the Bill

It's the summer's hottest country music ticket … Miranda Lambert and Blake Shelton are both headlining the 2015 WE Fest in August, and no one's bailing despite their nasty divorce.

Promoters for the Minnesota festival confirm neither Blake nor Miranda have bowed out.

Miranda is set to take the stage on Aug. 7, and Blake the next night. We're told there's little chance they'll cross paths. It's common for artists to fly in and out the day of their performance.

As we previously reported, it hasn't been an amicable split, but news of their divorce hasn't exactly hurt ticket sales ... they're almost sold out.

Bottom line ... the show will go on, but a duet is not in the cards.
