Miranda Lambert's latest show was full of emotion.

The 32-year-old singer got teary-eyed while singing "Over You," the 2012 duet she co-wrote with her ex-husband, Blake Shelton, during her concert at the Hollywood Casino Amphitheatre in Tinley Park, Illinois, on Friday.

The waterworks were also in full force later in the show, when the country crooner performed "The House That Built Me." Again, fans cheered her on by singing the touching lyrics.

Concertgoers later took to Twitter to share their opinions on the Chicago-area stop of Lambert's Keeper of the Flame Tour, writing things like, "Every time I see @mirandalambert I cry" and "@mirandalambert made me cry from her crying."
