Singer Miranda Lambert says she could use alcohol to lift her spirits after divorce from fellow musician Blake Shelton.

The 31-year-old star spoke of the need for alcohol while performing on stage at WE Fest 2015 in Detroit Lakes, Minnesota, on Friday, reports dailymail.co.uk.

`I wish I've been drinking all day, I deserve it - I just got divorced,` Lambert said.

Several fans in the audience tweeted what the singer said on stage and the effect was noticeable when one added, `My heart can't take this`.

This was Lambert's first big performance since splitting from Shelton last month after four years of marriage.
