Jessica Simpson shocked fans at a concert in Michigan on Thursday night with a series of onstage blunders - with the star eventually walking off in tears.
The singer was opening for Rascal Flatts at the Van Andel Arena in Grand Rapids, Michigan, but the 38-minute show was riddled with embarrassing errors which eventually forced her to apologize to the audience.
Simpson is said to have struggled with her in-ear audio monitors throughout the performance and seemed to lose her place in several songs, forgetting the lyrics to her recent single Come on Over.
The star also stopped during the intro to her Pray Out Loud track, asking her band start over, before mouthing the word "sorry" to the crowd, telling the 8,000-strong audience, "My voice is weak tonight."
While introducing her closing song, Do You Know, Simpson admitted wishing she could "walk off the stage" and at the end of the gig, she thanked her band for "having her back", before appearing to walk off in tears.
One concert-goer tells the Grand Rapids Press, "I felt bad for her tonight. It was uncomfortable to watch."
Simpson previously came under fire for her onstage antics following a performance at the Kennedy Center Honors in 2006, when she performed Nine to Five, a tribute to Dolly Parton, but stopped half way through the song, running off stage in tears.
Simpson put her blunder down to nerves and subsequently admitted she nearly quit her music career following the incident.
