Lady Antebellum are playing for laughs as they help raise awareness for cancer treatment and prevention. The hitmaking trio have released a video of them singing a parody of 'All About That Bass' for No Shave November.

During November, participants sign up individually or in teams and go without shaving for the entire month, documenting their progress through time-stamped pictures. St. Jude raised $400,000 in the first three years of the event. The goal for 2014 is to raise $200,000.

Lady A are doing their part by recording themselves singing Meghan Trainor's viral hit, but changing the words to 'All About That Beard (No Stubble).'

The group's No Shave November campaign will benefit St. Jude's Kids. For more information on how to register or donate, click here.

The philanthropic trio also founded their own charity, LadyAID, to help children locally, nationally and globally, with a focus on children's hospitals. This past fall, they also launched the 7FOR7 campaign, which granted the wishes of seven fans in seven days. They are slated to receive the Artist Humanitarian Award at the 2015 Country Radio Seminar in Nashville.
