Ashley Monroe took the stage with Miranda Lambert this week in Nashville, and the good friends embraced after their set even as speculation runs rampant online about Lambert’s divorce from fellow country star Blake Shelton.

Monroe–who performs with Lambert in their group The Pistol Annies–was celebrating her new album release this week when she performed at The Basement, and had Lambert come up on stage to perform a duet on “Heart Like Mine”. The good friends looked close at the event and Miranda was reportedly in good spirits during the set.

“Miranda looked amazing — was smiling, happy, dancing, singing. She is having a great time and is here to support a very good friend,” a source said.

Lambert is reportedly continuing on with her scheduled shows despite the announcement on Monday that she and Shelton are going their separate ways after four years of marriage; she’s due to play her own set in Nashville on July 28. Meanwhile, Miranda said in April that she and Ashley Monroe–along with their bandmate Angaleena Presley–may have some new music to share with fans soon.

“We’ve been texting a lot and just trying to figure [everything] out. When we get in a room, it’s magic, and so we just have to find time in our schedules… to just get in a room for a couple of days and I’m sure more magic will happen,” Lambert said.

Lambert and Shelton have been at the center of a whole lot of rumors this week, with sources telling the media that one or both of them cheated on the other and that Shelton’s gig with The Voice had a hand in ruining their relationship due to the necessity of his presence in L.A., which Lambert reportedly “hates”. However, neither have commented publicly on the rumors. Both have already changed their social media profiles to edit out the presence of the other.
